Igor Demin, Horlivka's police chief, told AFP news agency on Wednesday the rebels had taken control of the police headquarters in the town, which they declared part of the "People's Republic of Donetsk".

The seizures extended the grip of pro-Russian armed rebels on the town, who took over another police station on April 14.

regional governors in Kiev.
"The Russian leadership is doing everything to prevent the election. But the election will take place on May 25," he said.
Turchynov said the Ukrainian army was on full combat alert as "the threat of Russia starting a war against mainland Ukraine is real".
