North Korea

North Korea reportedly tested two more short-range missiles Tuesday, a day after detonating a nuclear bomb underground, pushing the regime further into a confrontation with world powers despite the threat of U.N. action. Two missiles _ one ground-to-air, the other ground-to-ship _ with a range of about 80 miles (130 kilometers) were test-fired from an east coast launchpad, South Korea's Yonhap news agency reported, citing an unidentified government official.

Pyongyang also warned ships to stay away from waters off its western coast this week, a sign it may be gearing up for more missile tests, South Korea's coast guard said. North Korea is "trying to test whether they can intimidate the international community" with its nuclear and missile activity, said Susan Rice, U.S. ambassador to the United Nations. Wall Street was lower in early trading as North Korea's actions kept investors on edge.

"But we are united, North Korea is isolated and pressure on North Korea will increase," Rice said. On Monday, President Barack Obama assailed Pyongyang, accusing it of engaging in "reckless" actions that have endangered the region, and the North accused Washington of hostility. France called for new sanctions, while the U.S. and Japan pushed for strong action against North Korea for testing a bomb that Russian officials said was comparable in power to those dropped on the Japanese cities of Hiroshima and Nagasaki in World War II.
