North Korea detains another American citizen, alleges hostile acts

North Korea has detained another American citizen accused of committing unspecified hostile acts against the country.The country's official Korean Central News Agency said Kim Hak Song was detained on Saturday and that "a relevant institution is now conducting a detailed investigation into his crimes."

He worked at Pyongyang University of Science and Technology, the same workplace as another American, accounting instructor Kim Sang Dok, whose detention was announced last Wednesday. The KCNA didn't say whether the two cases are connected.

The university said in a statement early Monday that Kim Hak Song was doing agricultural development work at an experimental farm. It said his detention was not related to his work at the university and therefore it could not comment further.

In Washington, the State Department said it was aware of the report of the new detention and that "the security of US citizens is one of the department's highest priorities."

Kim Sang Dok, the former accounting instructor at the Pyongyang university, was arrested at the Pyongyang International Airport on April 22, the KCNA said. It said he was "intercepted for committing criminal acts" to overthrow the North's government, but didn't elaborate.

The Pyongyang University of Science and Technology is the only privately funded university in North Korea and is unique for having a large number of foreign staff.

South Korea, the US and others often accuse North Korea of using foreign detainees to wrest diplomatic concessions, which have sometimes involved high-profile Americans sent to secure the release of the Americans.

Two other Americans detained in North Korea are Otto Warmbier, serving a 15-year prison term with hard labour for alleged anti-state acts, and Kim Dong Chul, serving a 10-year term with hard labour for alleged espionage.

When an American citizen is reported detained, the US works with the Swedish Embassy in the North Korean capital, since the US and the North do not have diplomatic relations.

North Korea's announcement of the detainments comes amid tensions over fears that Pyongyang is preparing another round of nuclear or missile tests and comments. US President Donald Trump has further spiked animosity by saying he isn't ruling out military action against the North, although Trump has also said he would be willing to talk with North Korean leader Kim Jong Un under the right circumstances.

North Korea on Friday accused the US and South Korean spy agencies of an unsuccessful assassination attempt on leader Kim Jong Un, involving biochemical weapons.
