Russian missile strikes on a town in the eastern Ukrainian Donetsk region killed three people overnight, including one child, officials said.
Donetsk Governor Vadym Filashkin said 12 people were injured and a five-story building and a hospital building were destroyed in the town of Selydove.
The war-torn region has come under heavy shelling almost daily, according to reports by local officials.
Separately, Ukraine's military said Wednesday it destroyed a Russian landing ship in the Black Sea, off the coast of occupied Crimea. CNBC was unable to independently verify the reports.
Meanwhile, U.S. lawmakers are continuing to debate the future of a major bill which would provide $61 billion for Ukraine. The national security act was approved by the Senate on Tuesday, but now faces the more difficult task of being approved in the Republican-led House of Representatives.
Senate majority leader Chuck Schumer said Tuesday he was confident the bill, which also provides assistance for Israel and U.S. allies in Asia-Pacific, could be passed. However, it remains strongly opposed by many Republicans, who say it has not included their demands for U.S. border security measures.
The issue has received international attention. During a visit to Bulgaria, U.K. Foreign Minister David Cameron urged U.S. lawmakers to pass the bill, calling it vital for American security.
NATO Secretary-General Jens Stoltenberg told a news conference that he welcomed the European Union's recent approval of further Ukraine aid, and said he was counting on the U.S. to follow suit.
"This is not charity, this is an investment in our own security," he said.
