Vasyl Krutov, the head of Ukraine’s anti-terrorist center, confirmed there was heavy fighting in Kramatorsk, a town 10 miles from Sloviansk.

“There is gunfire and clashes around Kramatorsk … What we are facing in the Donetsk region and in the eastern regions is not just some kind of short-lived uprising, it is in fact a war.”

In a later statement he added that Ukrainian forces have retaken the security service headquarters in Kramatorsk.
