KRAMATORSK, Ukraine — At least seven civilians were killed and more than a dozen wounded in a rocket attack on the Kiev-controlled eastern Ukrainian city of Kramatorsk on Tuesday, regional authorities reported.

The attack happened midday and as residents here returned to offices from lunch. At a café where Mashable was dining, about one mile away from the scene of the attack, the rumbling of a series of violent explosions shook its very foundation, and sent a dozen patrons screaming out the door and under their tables.
