Donetsk (Ukraine) (AFP) - Shelling was heard near the airport of the main rebel-held city of Donetsk in eastern Ukraine on Sunday, an AFP journalist in the area said.

It was not immediately clear who was behind the artillery fire, the latest breach of a shaky ceasefire signed on Friday. Although Donetsk itself is in the hands of the pro-Russian insurgents, the airport is controlled by Ukrainian government forces.
