A defiant North Korea on Tuesday fired two more short-range missiles from its east coast, heightening tension world-wide after its latest nuclear bomb test drew global condemnation.
A pair of short-range missiles -- one surface to air and one surface to water with the range of 130 kms -- were fired from its east coast launch pad, Yonhap news agency reported quoting an unnamed government official in Seoul.
Monday's underground nuclear test was followed by firing of three short-range missiles on the east coast hours later, a South Korean defence official said.
The communist nation had restricted ships off its west coast and cleared the waters off the northwestern coast, South Korean defence sources had said on Monday adding that the DPRK was "planning to launch anti-ship cruise missiles either Tuesday or Wednesday".
The UN Security Council held an emergency meeting to discuss strengthening sanctions on the North after Pyongyang on Monday conducted its second nuclear test which was estimated to be as powerful as the bombs that ravaged Japan's Hiroshima and Nagasaki in 1945.
