North Korea launches second suspected ballistic missile in a week

North Korea fired a suspected ballistic missile into the sea, South Korea's military said Tuesday, ratcheting up tensions less than a week after Pyongyang reported testing what it said was a hypersonic missile.

The early-morning launch came as the United Nations Security Council met in New York to discuss last week's test of what Pyongyang called a hypersonic missile, although Seoul has cast doubt on that claim.

After an emergency meeting, South Korea's national security council expressed "strong regret over the launch," according to a statement from the president's office.
