Oct. 9 (Bloomberg) -- North Korea accused South Korean naval ships of violating its territorial waters on the west coast, warning of a possible clash.

The situation has ``become so tense that a naval clash may break out due to such military provocations as the ceaseless infiltration of warships deep into the North Korea's territorial waters,'' the official Korea Central News Agency reported today, citing a spokesman for the Navy Command.

The report came after North Korea fired two short-range missiles off in the Yellow Sea on the peninsula's west coast on Oct. 7. The missiles were probably part of regular military exercise, a South Korean official said on Oct. 8.

A clash of the two navies in June 2002 resulted in the deaths of six South Korean sailors.
