Russia blocks UN statement criticising violence in eastern Ukraine's Mariupol

UNITED NATIONS (REUTERS) - Russia blocked a UN Security Council statement on Saturday that would have criticised a pro-Russian Ukrainian rebel leader and condemned a recent upsurge in violence that has claimed dozens of lives in eastern Ukraine, council diplomats said.

A revised version of the draft statement, obtained by Reuters, specifically named Alexander Zakharchenko, head of the rebels' self-proclaimed Donetsk People's Republic in eastern Ukraine, who made clear on Friday the separatists did not want compromise as they were now advancing.

On Saturday, Zakharchenko said the Mariupol offensive was "the best possible monument to all our dead" and promised further military advances.

Referring to Zakharchenko, the draft statement "condemned in the strongest terms such irresponsible announcements."

The council has been deadlocked on Ukraine since the start of the conflict a year ago. Russia, which Western council members accuse of sending troops and weapons to bolster the separatists in Ukraine, has veto powers and can block all council action. Moscow denies directing the rebels.

Fighting has escalated in eastern Ukraine in recent days, and Russian President Vladimir Putin has blamed Kiev. The rebels have ruled out more peace talks. Western powers and Kiev blame Russia and the rebels for the fresh fighting.

Ban's press office issued a statement saying he "strongly condemns today's rocket attack on the city of Mariupol, which reportedly killed dozens of civilians and left over one hundred injured."

It also said Ban "denounces yesterday's unilateral withdrawal from the ceasefire by rebel leadership, and particularly their provocative statements about claiming further territory." He said the separatists' actions violated a peace agreement negotiated in September in Minsk, Belarus.

Britain proposed a Security Council statement that would have echoed Ban's condemnation and called for an investigation into the attacks on Mariupol but Russia rejected it, diplomats said. Council statements need unanimous approval, which means all 15 members have the ability to strike them down.

"Russia have just blocked a UNSC (Security Council) statement by refusing to include condemnation of recent provocative public statements by the separatists," a council diplomat told Reuters on condition of anonymity.

The Russian UN mission did not have an immediate response to a request for comment.
