Russian Foreign Minister Sergey Lavrov is pushing for European powers to get Ukraine to comply with a truce in eastern Ukraine.

The already shaky truce between government troops and Russia-backed rebels in eastern Ukraine was thrown into question this week when overnight shelling from both sides killed at least nine people. Moscow blamed Kiev for surge of violence while Kiev said the rebel fighters provoked it.

The leaders of Ukraine, Germany and France are to meet Monday to discuss the uptick in fighting.

Lavrov said Wednesday that he hopes Germany and France, as signatories of the February truce, "will do everything to make sure" Kiev complies with the deal. The truce calls for the withdrawal of large-caliber weapons from the front line and reforms to devolve power to Ukraine's regions.
