Ukraine military blames rebel bomb for patrol boat explosion

KIEV (Reuters) - An explosion which sank a border patrol boat off Ukraine's strategically important port city of Mariupol was caused by a separatist-made bomb, the Ukrainian military said on Monday.

The boat exploded on Sunday, killing one crew member and wounding five others, as it left its mooring station in Mariupol, which is on the Sea of Azov and on the edge of the conflict between Ukrainian forces and Russian-backed separatists.
