North Korea test-fired 16 short-range rockets into the sea on Sunday, the South’s military said -- the latest of dozens launched in recent weeks in apparent protest at joint drills between Seoul and Washington.
The launches took place between about 1.00am and 2.30am off the North’s east coast, a South Korean defence ministry spokesman told AFP.
It is not unusual for Pyongyang to carry out such tests but there has been a spate of them in recent weeks. About 70 short-range rockets have been fired into the sea this month, including 30 on Saturday.
Analysts say the launches are an expression of Pyongyang’s anger at ongoing annual South Korean-US military drills, which run until next month.
The North has habitually criticised the exercises, along with other military drills staged south of the border, as practice for an invasion. Seoul and Washington insist they are purely defensive in nature.
South Korea and the United States have called for an end to the “provocative tests”.
As tension rise on the peninsula, the South’s President Park Geun-Hye is expected to hold a summit with Chinese leader Xi Jinping to reportedly discuss issues including curbing the North’s nuclear ambitions.
Park and Xi will meet Sunday evening on the sidelines of a nuclear security summit to be held in Hague, Park’s spokesman told reporters.
During their fourth summit, the two leaders are expected to discuss issues including the North’s nuclear arsenal, Yonhap news agency said.
China is the isolated Pyongyang’s sole major ally and economic lifeline and is seen as a key player in resolving the nuclear standoff with the North.
The six-nation nuclear disarmament talks on the North -- chaired by Beijing -- have been stalled since 2008.
Earlier this month, the North’s powerful National Defense Commission threatened to demonstrate its nuclear deterrent in the face of what it called US hostility.
Seoul’s defence ministry said there was no sign yet of an imminent nuclear test by the North, which staged three atomic tests in 2006, 2009 and last year.
