A separatist leader in eastern Ukraine has called on residents to evacuate to Russia.
Denis Pushilin, the head of the self-proclaimed Donetsk People's Republic (DPR), said in a statement that the recommendation to evacuate is due to the "sharp aggravation" of the military situation.
He accused Ukrainian forces of having amassed "troops and lethal weapons" along the line of contact and claimed that the army is now "in combat formation and ready to seize Donbas by force."
"The lives and health of our citizens may be endangered if the enemy shells populated areas of the Republic.

He added that the evacuations have been organised in coordination with Moscow with "reception and accommodation facilities for our citizens are ready in the Rostov region."
"All conditions have been created for a quick transition at the checkpoints," he continued.
Women, children and the elderly are to be the first to be evacuated.
