Ukraine's military intelligence tweeted on Friday that they have information that mines have been planted in a number of social infrastructure facilities in separatist-controlled Donetsk by Russian special forces.
"These measures are aimed at destabilizing the situation in the temporarily occupied territories of our state and creating grounds for accusing Ukraine of terrorist acts," the Defence Intelligence of Ukraine said in its official Twitter account.
"The Defence Intelligence of the State Security Service of Ukraine urges Donetsk residents not to leave their homes and not to use public transport," it tweeted.
Russian-backed separatists announced an evacuation earlier on Friday and packed civilians onto buses out of breakaway regions in east Ukraine in a conflict the West believes Moscow plans to use as justification for an all-out invasion of its neighbor.
