Mariupol in south-eastern Ukraine, 6 Sept 
Russia has vowed to respond if the European Union imposes new sanctions over the Ukraine crisis.            
 The EU says the sanctions, targeting more Russian individuals, will come in on Monday but could be later suspended if Russia withdraws troops from eastern Ukraine and observes a current truce.
Friday's ceasefire appears to be largely holding - but there were reports of shootings by both sides.
Some 2,600 people have died since a pro-Russian rebellion began in April.
  
'Party of war'
The Russian foreign ministry said in a statement: "As for the new list of sanctions from the European Union, if they are passed, there will undoubtedly be a reaction from our side."

Ukrainian forces have been losing ground to the rebels in the past two weeks.
The fresh sanctions would add another 24 people to the list of people barred from entering the EU and whose assets have been frozen.
Among them would be the rebel leadership in the eastern Donetsk and Luhansk regions, officials in Crimea, which was annexed by Russia in March, and Russian "decision-makers and oligarchs", European Council President Herman Van Rompuy and European Commission chief Jose Manuel Barroso said in a statement.

The two sides, meeting in the Belarusian capital Minsk, agreed to stop firing at 15:00 GMT.
President Petro Poroshenko said he would do "everything possible" to end the bloodshed. The rebels said the truce had not changed their policy of advocating separation from Ukraine.
More than 2,600 people have died since rebels stormed several eastern cities.
The move prompted a military operation by Ukrainian forces to retake the cities.
The rebels, who had largely been pushed back towards their strongholds of Donetsk and Luhansk, made new advances in recent days.
Fighting was continuing on Friday around Mariupol, a coastal city about 110km (70 miles) south of Donetsk.
The BBC's Fergal Keane in Mariupol tweeted that pro-Russia forces seemed to be hitting Ukrainian positions 4km outside the city.
Large plumes of smoke could be seen as Ukrainian artillery fired back, he says. Ukrainian fighter jets also hit rebel positions.
The West accuses Russia of sending arms and troops to back the rebels in eastern Ukraine - allegations denied by Russia.


The leader of pro-Russian rebels in Donetsk said Saturday he believed the Malaysian commercial jet that crashed in eastern Ukraine was shot down, but Alexander Borodai reiterated his denial that his forces did it.

Two days after Malaysia Airlines Flight 17 crashed to earth in eastern Ukraine, the grim task of gathering the remains of some of the 298 victims of the disaster in body bags ready for removal was under way.
Artillery fire could be heard in the near distance from the crash scene, where a team of observers from the Organization for Security and Cooperation in Europe gained access Saturday for a second day.
OSCE spokesman Michael Bociurkiw, briefing reporters from the scene, said the observers were still being denied access to certain areas but that their movements were freer than the previous day, when they were met with hostility by rebels.
He said that experts now have professional body bags and are gathering body parts in them. The bags are being left by the road for collection.

The fields where the plane came down Thursday, near the town of Torez, are in a volatile rebel-controlled area of the eastern Donetsk region, making access to the scattered debris and body parts difficult.
The United States said a surface-to-air missile, possibly fired by pro-Russian rebels, took down Malaysia Airlines Flight 17. The plane, which had 298 people aboard from 11 nations, was traveling from Amsterdam's Schiphol Airport to the Malaysian capital of Kuala Lumpur.
Since the crash, the Ukrainian government and pro-Russia rebels have traded bitter accusations over who was responsible and what has been done since.
A rebel leader denied claims Saturday by the Ukrainian government that the rebels had already removed 38 bodies from the scene and taken them to a morgue in the rebel stronghold of Donetsk.
Alexander Borodai, Prime Minister of the self-declared Donetsk People's Republic, told a news conference in Donetsk that the rebels had not removed any bodies from the crash site, and that they are waiting for international experts to act.
"There is even a house where a body fell, the landlord asked us to remove and we haven't because we are not allowed to move anything," he said.
An international organization at the scene Friday said it appeared that the bodies have not been tampered with.
Looting claim
Ukraine's government also said it had received information of looting of various items, including money and jewelry, and urged relatives to cancel the victims' credit cards.
But a CNN crew at the scene Saturday said it did not see any signs of looting or the rebels rummaging through items at the crash site. Pro-Russian rebels have been moving around the site since the plane crashed.
A government statement also accused the rebels of "seeking to export large-sized transport aircraft wreckage to Russia."
It appealed for the international community to put pressure on Moscow to rein in the rebels, saying, "Russia is supporting terrorists in their attempts to destroy evidence of international crime."

Ukrainian officials also repeated their claim Saturday that Russia had been involved in the shooting down of the Boeing 777.
Vitaly Nayda, counter-intellligence chief for Ukraine's Security Service Counter-Intelligence Chief, told reporters in Kiev that a Russian-made Buk M1 missile system had shot down MH17 and showed a photo of what he claimed was the smoke trail of the missile fired.
Nayda claimed that three Buk missile systems had crossed from Russia to Ukraine prior to the downing of MH17, accompanied by Russian citizens who, he said, were the ones operating the sophisticated weaponry. Nayda said that all three Buk surface-to-air anti-aircraft missile systems have now left Ukrainian territory.
Prime Minster Arseniy Yatsenyuk, in an interview with CNN on Saturday, also suggested that whoever operated the missile system had had expert training.
"This is not the Russian-led drunk terrorist who pressed the button," he said. "This is someone well trained. Someone who knows how this machine works. Someone who has experience."
Ukraine and the international community "will find out all responsible for this international crime, and those who supported them, because this is (a) crime against humanity, and the building of (the) international criminal court is very big," Yatsenyuk added.
One key issue for investigators is the location of the plane's flight data recorders, which may hold crucial data.
The Ukraine government said Friday that the black boxes for MH17 are still on the territory of Ukraine, although they have not clarified whether they have control of the boxes.
Russia's President Vladimir Putin has said Ukraine's military campaign against the separatists was to blame. He also has called for a "thorough and objective investigation" of the crash.
Hostility, fresh clashes
German Chancellor Angela Merkel asked Putin in a phone call Saturday to exert his influence on the pro-Russia rebels to allow crash investigators free access to the site, a German government spokesman said.
Putin and Merkel agreed on the importance of a ceasefire between the pro-Russian separatists and Ukraine's government, the spokesman said.
Bociurkiw told reporters Saturday that the observers have seen that large pieces of debris have not been disturbed, but much of it is badly burned, he said.
At the same time, he said, they have come across duty-free bags with bottles of liquor from Schiphol Airport that are still intact.
When a larger, 21-strong OSCE team arrived among the blackened debris on Friday, armed local militiamen greeted them with hostility and limited their access to the site, he said.
"There didn't seem to be anyone really in control," said Bociurkiw after that visit.
Bociurkiw said the group only stayed about 75 minutes and examined about 200 meters at the scene Friday before being forced to leave. Pieces of the airplane and bodies are spread over several kilometers.
But, he added, "I don't think too much of the crime scene has been compromised already. The bodies are still there. They have not been tampered with. We actually spoke to some civilian emergency workers. They said their job was just to mark where the bodies are."
In an indication of the volatility of the region, at least five Ukrainian soldiers were killed and 20 wounded in the past 24 hours in clashes with pro-Russian separatists only 100 kilometers from the debris fields, Lieutenant Colonel Vladislav Seleznyov told CNN on Saturday.
Fighting is taking place around the Luhansk airport and the Metalist neighborhood of Luhansk, said Seleznyov, a Ukrainian military spokesman. The pro-Russian separatists are firing with heavy artillery, mortars and Grad rockets, he said.
'We need to retrieve the human remains'
Malaysian investigators also touched down in Kiev on Saturday to try to get the bottom of what happened to the jetliner.
But Malaysia's official news agency Bernama said they were still negotiating with pro-Russian rebels over access for their 131-member team.
Malaysian Transport Minister Liow Tiong Lai insisted Saturday in Kuala Lumpur that Malaysia must have full, safe access to the crash site, and that it is "deeply concerned that the crash site has not yet been properly secured."
The site's integrity has been compromised, Liow said, and "there are indications that vital evidence has not been preserved in place."
He warned that interference with the crash scene risked undermining the investigation into what happened. Bodies are also not being treated with proper respect.
The transportation minister said he and other senior officials would also travel to Kiev to support the Ukrainian authorities in their investigation.
"Since the plane went down, the remains of 298 people lie uncovered. Citizens of 11 nations, none of whom are involved in the conflict in eastern Ukraine, cannot be laid to rest," he said.
"We need to retrieve the human remains as fast as we can."

An international tragedy
The full list of the passengers was released Saturday. According to a final breakdown from Malaysia Airlines, 193 of those killed were from the Netherlands, including one who had dual U.S.-Dutch citizenship.
There were also 43 victims from Malaysia, including the plane's 15 crew; 27 from Australia; 12 from Indonesia; 10 from the United Kingdom, including one who had dual UK-South African citizenship; four each from Germany and Belgium; three from the Philippines and one each from Canada and New Zealand.
Eighty of the victims were children, the United Nations said.
In the Netherlands, dozens of police officers are now visiting all the families of the victims. They will gather specific information that will help identify the victims, such as DNA samples, details of tattoos and dental records, the Dutch police said. A Dutch forensics team has already arrived in Ukraine.
The FBI is sending two investigators to work on the case, a U.S. law enforcement official said, but the Ukraine government will be in charge of the investigation.
Australia is sending six foreign affairs officers to Kiev to assist in the investigation, the country's Prime Minister Tony Abbott said Saturday.
The Kremlin has criticized Abbott over his harsh words on possible Russian involvement in the tragedy. He repeated them Saturday.
"Australia takes a very dim view of countries which facilitate killing of Australians, as you'd expect us to. We take a very, very dim view of this and the idea that Russia can wash its hands of responsibility, because this happened in Ukrainian airspace, just does not stand serious scrutiny," Abbott said.
Obama's focus on Russia
Russia likely bears some of the responsibility for the apparent downing of Flight 17, U.S. President Barack Obama said Friday.
Obama said rebel fighters couldn't have operated the surface-to-air missile believed responsible for the shootdown "without sophisticated equipment and sophisticated training, and that is coming from Russia."
He and other U.S. officials stopped short of publicly placing the responsibility on Russia, which has denied involvement in the destruction of the jetliner.
But a senior defense official told CNN that the "working theory" among U.S. intelligence analysts is that the Russian military supplied the Buk missile system to rebel fighters inside Ukraine.
Among the evidence cited by U.S. officials and others for their conclusions was an audio recording released by Ukrainian intelligence officials that purportedly featured pro-Russian rebels and Russian military officers discussing a surface-to-air strike.
CNN cannot confirm the authenticity of this audio, or other similar recordings.
A day before MH17 came down, Obama announced expanded sanctions against a number of major Russian companies in response to Russia's actions in Ukraine.
In an apparently retaliatory move, Russian Foreign Ministry spokesman Alexander Lukashevich said Saturday that Russia had added the names of a number of American citizens to a list that bans them from entering Russia.
Russia-Ukraine dispute
Tensions have been high between Ukraine and Russia since street protests forced former pro-Moscow President Viktor Yanukovych from power in February. Russia subsequently annexed Ukraine's southeastern Crimea region, and a pro-Russian separatist rebellion has been raging in Ukraine's eastern Luhansk and Donetsk regions.
Ukraine has accused Russia of allowing weapons and military equipment, including tanks, to cross the border illegally into the hands of pro-Russian rebels.
