AP, Paris :Talks about a fragile peace deal for Ukraine ended in tension Tuesday, with differences over who is at fault over continued violence despite a cease-fire.The foreign ministers of Russia, Ukraine, Germany and France met in Paris amid uncertainty that the accord will hold – in particular a promised withdrawal of heavy weapons from the front line.Ukraine delayed the pullout Monday, blaming continuing attacks from separatist rebels in eastern Ukraine.German Foreign Minister Frank-Walter Steinmeier described the talks as difficult.Ukrainian Foreign Minister Pavlo Klimkin emerged grim-faced, saying they agreed on some “technical aspects” including more support for an OSCE monitoring mission – but didn’t reach an agreement on condemning recent violence in the town of Debaltseve or who is at fault for continuing sporadic violence despite a cease-fire.Under a peace agreement reached Feb. 12 by France, Germany, Russia and Ukraine, both sides must withdraw their heavy weapons between 25 and 70 kilometers (15 to 45 miles) to create a buffer zone.Sergey Lavrov of Russia said the discussion focused on the implementation of the peace deal.”The most important thing is to ensure the cease-fire,” he said according to Russian news agencies.Fabius said they want to extend the OSCE mandate. He said all four “remain determined to continue action in this for mat and do the utmost to ensure” that promises are kept. Meanwhile, wounded rebel fighter Islam Alibaterov limps painfully along the corridor of the hospital in the separatist-held town of Novoazovsk in east Ukraine.Like others in the growing stream of insurgents now filling up the beds here, he was injured as fighting with Ukrainian forces flared up in recent days just outside the key government-held port city of Mariupol.Despite the nominal truce in force, the key industrial hub has become the latest hotspot in the conflict in east Ukraine, stoking fears that pro-Russian rebel forces could be gearing up to try to seize the city.”I was wounded by the explosion of a mortar,” Alibaterov told AFP as he inched towards his room.”A pile of bricks fell on me while a sniper was shooting at me. I found two bullets in my bulletproof vest.” Once in his room, he displays the impact on the black vest.Alibaterov, 29, — who claims he came as a volunteer from his home region of Dagestan in Russia to fight with the rebels-recounted how the fighting has focused on the tiny village of Shyrokine, some 15 kilometres east of Mariupol.”The bombardments in Shyrokine happen every day. Last week we had some dead,” said the soldier, as a nurse gave him a roll of toilet paper and bar of soap.
