North Korea tests new 'high-thrust' rocket engine

North Korea "acting very, very badly" Spicer: Trump didn't hear Merkel's handshake request Hawaii judge refuses to narrow travel ban halt MORE slammed North Korean dictator Kim Jong Un on Sunday for "acting very, very badly", following that country's recent missile activity.

The possession of strong nuclear weapons is "the only way" to ultimately put North Korea-U.S. relations in order and "absolute collateral" for peace and security on the Korean Peninsula, the paper said.

"He's acting very very badly", the president said of Kim Jong Un, according to a White House pool report.

Trump made the comments to reporters while departing his Mar-a-Lago resort in Florida, US, where he spent the weekend.

The reported test came one day after U.S. Secretary of State Rex Tillerson warned that the U.S.is contemplating a pre-emptive military attack on North Korea and as he was traveling to Beijing.

It took place at the Sohae Satellite Launching Ground, in North Pyongan Province, it said.

Earlier this month, North Korea fired off four ballistic missiles into the Sea of Japan, reportedly reaching within 120 miles of Japan's shoreline.

The paper also claimed that the firing of a new intermediate-range ballistic missile (IRBM), called Pukguksong-2, on February 12 and four ballistic missiles on March 6 were steps to fight "constant USA invasion intimidations". North Korean officials said they will launch more Earth observation satellites and are building a space program that would include a moon launch in the next 10 years.

China has also been infuriated by the deployment of an advanced US anti-missile system in South Korea, which it says will both harm China's own security and do nothing to ease tensions.

In Seoul, Tillerson also warned that U.S. military action against Pyongyang was possible - a sharp divergence from China's insistence on a diplomatic approach to its neighbour, which it has long protected.
