US spots ‘unusual and unprecedented’ North Korean submarine activity

The U.S. military has spotted “highly unusual and unprecedented levels” of North Korean submarine activity, CNN reported.

A defense official told the network Monday that there was also evidence of an “ejection test,” which looks at the “cold-launch system” of a missile.

The system uses “high pressure steam to propel a missile out of the launch canister,” according to CNN.

The report comes after North Korea last week conducted another test of an intercontinental ballistic missile (ICBM).

The test — the nation’s second in less than a month — raised concerns about Pyongyang’s capabilities to strike the U.S. mainland.

Experts believe the ICBM could potentially hit the United States’ West Coast. American presidents have long vowed to prevent North Korea from gaining such a weapon.

On Monday, President Trump expressed confidence the U.S. would deal with North Korea.

“We’ll handle North Korea. We’ll be able to handle North Korea. It will be handled. We handle everything,” Trump told reporters during a Cabinet meeting at the White House.

Trump over the weekend voiced disappointment with China over its handling of the North Korea threat.
