Witnesses heard renewed artillery shelling to the east of the port of Mariupol in eastern Ukraine today, hours before peace talks are due to begin, Reuters reports.
"Our artillery has come and is being deployed against the (pro-Russian) rebels," the mayor of Mariupol, Yuri Khotlubey, told Ukraine's 112 TV channel.
A commander of a Ukrainian volunteer militia based in Mariupol told Reuters: "We were under fire all night but we are still keeping the rebels at bay. They are facing us with tanks and artillery."
Were the Russians -as Barack Obama claims - weighed down by sanctions, or where the Ukrainians looking to cut their losses?
The new president of the European Council could be "very important" for David Cameron.
