SEOUL, South Korea (AP) — The Latest on the failed launch of a North Korean missile Sunday from the country's east coast (all times local):

9:44 a.m.

President Donald Trump was uncharacteristically quiet about the failed launch of a North Korean missile from the country's east coast.

In a statement, Defense Secretary Jim Mattis says Trump and his military team "are aware of North Korea's most recent unsuccessful missile launch. The president has no further comment."

Trump has been leaning on China to put pressure on North Korea, but has also threatened to take on the country alone if necessary. "I have great confidence that China will properly deal with North Korea. If they are unable to do so, the U.S., with its allies, will!" he tweeted Thursday. "U.S.A."

A North Korean missile exploded during launch Sunday from the country's east coast, U.S. and South Korean officials said, a high-profile failure that comes as a powerful U.S. aircraft carrier approaches the Korean Peninsula in a show of force.

It wasn't immediately clear what kind of missile was fired from the city of Sinpo, but the failure will sting in Pyongyang because it comes a day after one of the biggest North Korean propaganda events of the year— celebrations of the 105th birthday of late North Korea founder Kim Il Sung, the current leader's grandfather.

Washington and Seoul will try hard to figure out what exactly North Korea fired. This matters because while North Korea regularly launches short-range missiles, it is also developing mid-range and long-range missiles meant to target U.S. troops in Asia and, eventually, the U.S. mainland.

South Korea's Joint Chiefs of Staff says that North Korea has attempted to launch a missile from an eastern coastal city, but the launch appeared to end in failure.

The statement Sunday said it wasn't clear what kind of missile was involved.

North Korea launched a long-range rocket and conducted two nuclear tests last year, including its most powerful to date, and there have been a slew of shorter range missile firings.

North Korea's goal is a long-range nuclear missile that can strike the continental United States.

Sunday's launch comes a day after the 105th birthday of late North Korea founder Kim Il Sung.
