Seoul, Rabi'II 29, 1437, February 08, 2016, SPA -- The South Korean military fired warning shots at a military vessel from the North that crossed their maritime border Monday, a news report said, according to dpa. The boat crossed the disputed boundary around 6:55 am (2155 Sunday GMT) in the Yellow Sea, to the west of the peninsula, before retreating 20 minutes later after the South's navy fired five warning rounds, an unnamed Seoul military official was quoted as saying by the Yonhap News Agency. North Korean vessels frequently cross the Northern Limit Line, which Pyongyang argues should be further south. --SPA 11:00 LOCAL TIME 08:00 GMT www.spa.gov.sa/w
