A large column of the Ukrainian army's armored vehicles is moving toward Kramatorsk in Donetsk region to support special forces units that are already in the city, a Ukrinform correspondent has reported on Wednesday.

According to eyewitnesses, the column consists of at least two dozen armored vehicles with paratroopers.

Before them, ten armored vehicles and airborne combat vehicles of the Armed Forces of Ukraine had already entered the city.

To recall, Ukraine's acting President Olexander Turchynov has announced the start of an "anti-terrorist operation" against pro-Russian separatists.

Ukrainian riot police already cleared Kramatorsk Airport of terrorists as part of the anti-terror operation.
