Warning Shots Fired As N. Korean Ship Crosses Inter-Korean Maritime Border

South Korean troops exchanged warning shots with North Korea, whose vessel crossed the maritime border between the two Koreas, Yonhap News Agency reports.

• South Korea's Joint Chiefs of Staff were quoted as saying that they fired warning shots as the North Korean ship crossed the northern limit line and Pyongyang's troops responded in kind.
• Experts have warned that North Korea could escalate military provocations after the congress of the Chinese Communist Party, which drew to an end on Sunday.
• This includes potential for a nuclear test, with Pyongyang believed to have completed all necessary preparations.
• The Korea Herald ran a piece citing military analysts who warned that North Korea would probably need more than one nuclear test to meet the requirements of its nuclear weapons programme.
