North Korea 'fires more missiles'
North Korea has test-fired two more missiles, hours after the UN Security Council unanimously condemned its nuclear test, South Korean reports say.
The communist state fired two short-range missiles off an east coast base, South Korea's Yonhap news agency reported, citing an official.
The move came as UN diplomats began work on a resolution to punish North Korea for its underground nuclear test.
Diplomats said they were seeking "tough measures", including further sanctions.
Mondays's nuclear test was accompanied by at least three missile tests.
The latest tests on Tuesday involved one surface-to-air missile and one ground-to-air missile, Yonhap said.
They came amid widespread international concern over Pyongyang's activities.
Late on Monday US President Barack Obama spoke to the leaders of both Japan and South Korea to assure them of America's commitment to security in North-East Asia.
