North Korea has test-fired two ballistic missiles, as US President Barack Obama hosted a landmark Japan-South Korea summit and pledged "unwavering commitment" to Tokyo and Seoul's security concerns in the face of Pyongyang's nuclear threat.
South Korea's defence ministry said both missiles flew 650 kilometres (400 miles) into the Sea of Japan, upping the ante after a series of short-range missile and rocket launches by the North in recent weeks.
A ministry spokesman said the missiles were believed to be Rodong variants, which are considered medium-range at their maximum reach of between 1,000 and 1,500 kilometres.
UN Security Council resolutions prohibit North Korea from conducting any ballistic missile tests.
The United States responded to North Korea's test firing, saying it represented "a troubling and provocative escalation."
