Fierce fighting has taken place between Ukrainian government forces and pro-Russian rebels in eastern Ukraine, officials on both sides say.
The clashes - said to involve heavy artillery and tanks - took place in Maryinka and Kras-no-ho-riv-ka, outside the rebel-held city of Donetsk.
There were reports of multiple injuries in the towns held by Ukraine's army.
Ukraine accused the rebels of launching a full-scale offensive in violation of a truce.
The separatists deny this.
