The U.S. Embassy to Ukraine on Sunday condemned the latest attack on a holy monastery in Eastern Ukraine that for months has housed refugees. In Kyiv, missile strikes hit a train-repair facility and other infrastructure.
The U.K. Ministry of Defence said Russia is using separatist forces in eastern Ukraine, which it said suggests Moscow is trying to limit casualties sustained by its own regular troops.
Both sides have claimed gains in territory and cities in Ukraine's eastern region as tough street fighting continues.
