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.
