In eastern Ukraine, fighting is intensifying between the Ukrainian army and pro-Russia separatists.
Both sides are battling for control of strategic positions in the region. Heavy shelling continues in the rebel-held strongholds of Donetsk and Luhansk.
A hospital in Donetsk was targeted on Wednesday, killing three and injuring many more.
The town of Debaltseve has become a flashpoint between the two sides, where heavy shelling is forcing many residents to flee. The town is an important transport hub between Russia and Ukraine.
