Russian forces are preparing for a "covert mobilization" in the eastern Donetsk region, the General Staff of the Armed Forces of Ukraine said Thursday on its official Facebook page. 

"In the temporarily occupied territories of the Donetsk region, Russia is preparing for covert mobilization. In particular, in the city of Horlivka, all budget and communal institutions were ordered to submit lists of necessary persons to the occupation military commissariat. All these people will be examined by special commissions of the enemy, with subsequent conscription into the ranks of the enemy," it said in the statement.

Russian forces continue "active reconnaissance and preparation for an offensive in several directions,” it said, adding that "offensive operations" continue toward Lyman, Bakhmut, Avdiiv and Novopavliv.

For context: Ukrainian officials have repeatedly warned that Russia planned on using its claimed annexations as a pretext to draft Ukrainians in occupied areas. In October, the military said Russian forces were carrying out “door-to-door” checks in occupied areas, looking for young men of conscription age.
