North Korea has yet again launched a ballistic missile near the east coast peninsula, South Korea’s Joint Chiefs of Staff (JCS) have claimed.

The JCS claimed the country had fired the missile from an area near Sondok airport, in Sondong-ni, North Korea. However, the officials could not confirm the range and trajectory of the missile.

The move comes during a two-day Nuclear Security Summit being hosted by US President Barack Obama in Washington.

Representatives from 56 nations and organisations will participate in the summit, which is believed to be focusing on securing nuclear and radiological material to avoid potential threats.

"We are united in our efforts to deter and defend against North Korean provocations."

Obama was quoted by CBC News as saying: "We are united in our efforts to deter and defend against North Korean provocations.

"We recognised that our security is linked, and that we have to meet together to meet this challenge."

The US, Japan, and South Korea have warned the nation to end its missile launches, which violate the UN protocol.

In January, North Korea conducted its fourth nuclear test and has test-fired several missiles since then.

Following the launch, the UN Security Council unanimously adopted Resolution 2270, imposing sanctions on North Korea.

Last week, South Korea blamed North Korea for sending radio waves to jam GPS signals in South Korea, according to NBC News.

However, any major disruption in the South Korean military, air and naval transport and telecommunication systems was not reported.
