South Korea says North Korea fired missile

North Korea fired another short-range missile off its east coast today, South Korean officials said, as regional leaders met in Washington to discuss the threat of Pyongyang's nuclear weapons programme.

It was the latest in a series of North Korean missile launches during what has been an extended period of elevated military tension on the Korean peninsula, triggered by Pyongyang's fourth nuclear test on January 6.

The launch came as the South Korean coastguard reported that around 70 fishing vessels had been forced back to port after GPS navigation issues caused by North Korean radio-wave jamming.

South Korea's defence ministry said the surface-to-air missile was fired at around 12:45 pm (0345 GMT) from the eastern city of Sondok. The range and precise trajectory could not immediately be confirmed, a ministry official said. The South's Yonhap news agency said it flew 100 kilometres (60 miles) into the East Sea (Sea of Japan).

The launch came in the middle of a two-day nuclear security summit being hosted by Barack Obama in Washington, at which North Korea has been the focus of



the US president's talks with the leaders of China, South Korea and Japan.

Obama spoke Thursday of the need to "vigilantly enforce the strong UN security measures" imposed on the North after its latest nuclear test and subsequent long-range rocket launch.

Pyongyang's state media has labelled the summit a "nonsensical" effort to find fault with the North's "legitimate access to nuclear weapons".

Existing UN sanctions ban North Korea from conducting any ballistic missile test, although short-range launches tend to go unpunished.

Last month, the North upped the ante by test-firing two medium-range missiles, which were seen as far more provocative given the threat they pose to neighbours like Japan.

Earlier Friday, Seoul said North Korea was using radio waves to jam GPS signals in South Korea, affecting scores of planes and vessels.

"GPS jamming is an act of provocation. We urge the North to stop such provocative acts and behave in a manner that would help improve inter-Korean relations," Unification Ministry spokesman Jeong Joon-Hee told journalists.
