N. Korea Escalates Tensions with More Missile Launches

The U.S. and South Korean governments are calling on North Korea to stop its provocative missile tests.

Officials in Seoul say North Korea launched five more short-range missiles into the sea Monday.

It's the latest in a series of missile launches by the North since South Korea and the United States began annual military drills.

This year's drills are the largest ever. They come after North Korea conducted a nuclear test and a long-range rocket launch earlier this year, leading the U.N. Security Council to impose its toughest sanctions on the country in two decades.

These latest launches also came three days after Seoul said North Korea launched its first medium-range ballistic missile into the sea since early 2014, ignoring U.N. resolutions against such tests.

Meanwhile, officials are also calling on North Korea to release imprisoned American student Otto Warmbier.

Warmbier was sentenced to 15 years in a labor camp for allegedly trying to steal a political banner from a hotel.
