A high-rise apartment block was hit by shelling overnight in Kiev as fighting raged between Russian and Ukrainian forces, emergency services said Saturday. 

The authorities said the number of victims was "being specified" and that an evacuation was underway. They posted a picture online of the tower block with a hole covering at least five floors blasted into the side and rubble strewn across the street below.

Kiev Mayor Vitaly Klitschko said online that the building had been hit by a missile.
