Ukrainian Prime Minister Arseniy Yatseniuk has demanded that protesters vacate the seized building of Donetsk Regional State Administration and surrender their weapons.

"I'm against any use of force. I am demanding that the illegally seized premises be vacated and that the weapons be surrendered," he said in Donetsk on Friday.

As reported, on April 6, activists of pro-Russian organizations seized the regional administration in Donetsk and barricaded themselves inside the building.
