Russian forces start battle for Donbas: Ukrainian president

KIEV, April 18 (Xinhua) -- Russian forces have begun the battle for the Donbas region, but Ukraine will defend itself, Ukrainian President Volodymyr Zelensky said in a video address on Monday.

"Now we can say that Russian troops have started the battle for Donbas, for which they have been preparing for a long time. A very large part of the entire Russian army is now focused on this offensive," Zelensky was quoted as saying by the state-run Ukrinform news agency.

"No matter how many Russian troops are driven there, we will fight," he added.

In the east and south of Ukraine, Russian forces have recently been trying to attack a little more deliberately than before and looking for a weak spot in the country's defense to go there with the main forces, Zelensky said.
