Ukrainian President Petro Poroshenko has urged the European Union to take tough action against Russia over the separatist conflict in Ukraine's eastern regions at a summit of EU leaders in Brussels on Wednesday.
Poroshenko's website said he had spoken to Herman Van Rompuy, President of the European Council, after intensified fighting in the east, in which Kiev has alleged Russian involvement in an air strike on a residential area and the downing of a military transport plane.
Poroshenko informed Van Rompuy of new evidence of rebel fighters crossing into Ukraine from Russia along with heavy military equipment and arms, his website said.
He had called on the EU "to demonstrate a strong position of action by the European Union to support Ukraine", it said.
Diplomats in Brussels say EU leaders are likely to give the go-ahead on Wednesday to new sanctions, though they may fall short of the far-reaching economic measures sought by the United States and by some of the more hawkish members of the EU, including Poland and the Baltic states.
Ukraine has accused Russia repeatedly of turning a blind eye to Russian fighters crossing the long shared border to team up with rebels, often with Russian weapons and military equipment. Moscow denies this.
But the war of words has grown more shrill since a shell struck a Russian town across the border last Sunday, killing a Russian man. Moscow said the shell had been fired by Ukrainian government forces, though Kiev denies this, blaming it on rebels out to discredit government forces.
Eleven people were said by local health authorities to have been killed on Tuesday in an air strike on the Ukrainian town of Snizhne, 20 km (12 miles) from the border.
Kiev denied rebel charges that the strike had been carried out by a Ukrainian warplane and said it was the work of an "unknown" plane - apparently an accusation against Russia, since the rebels have not used aircraft in the conflict.
Kiev has also said that a missile that brought down an An-26 military transporter was probably fired from Russian territory. Kiev says it has found four survivors from the eight people who were on board, that two others are being held by rebels, and that it does not know the fate of the remaining two.
Since the Kiev government launched its "anti-terrorist" operations in mid-April, a total of 258 Ukrainian servicemen have been killed, and nearly 1,000 injured, the military says. Hundreds of civilians and rebels have also died.
Violence erupted in Ukraine's Russian-speaking east after a pro-Europe revolt in Kiev that ousted a Moscow-backed president in February and led to Russia's annexation of Crimea, causing the biggest Russia-West crisis since the Cold War.
International positions:
The German government criticized Russia on Wednesday for failing to meet commitments agreed earlier this month on de-escalating the violence in Ukraine and said the European Union remained ready to impose further sanctions on Russia if necessary.
European Union leaders are weighing new sanctions against Russia as Moscow has not done enough to bring about peace in Ukraine, German Chancellor Angela Merkel said.
"We will talk about new sanctions because we believe that the Russian contribution to peace in Ukraine is not sufficient." Merkel told reporters as she arrived for an EU summit in Brussels.
EU leaders want to block loans for new projects in Russia by two multilateral lenders and broaden the scope of other sanctions in response to Moscow's actions in Ukraine, according to a draft summit statement seen by Reuters.
