US asks North Korea to immediately release American student

Otto Warmbier, a student at the University of Virginia, was arrested on charges of 'hostile acts' against the state

The US has asked North Korea to immediately release its national, who was jailed for 15 years with hard labour for subversive activities after stealing a propaganda banner, and accused the reclusive nation of using imprisoned Americans as "pawns to pursue a political agenda".

Otto Warmbier, a student at the University of Virginia, was arrested in North Korea in early January on charges of "hostile acts" against the state, according to the country's official news agency KCNA.

He was yesterday sentenced to 15 years in prison with hard labour, KCNA said.

The White House asked the North Korean regime to pardon Warmbier.

"Now that Mr Warmbier has gone through this criminal process, we strongly urge the North Korean government to pardon him and grant him special amnesty and immediate release," White House Press Secretary Josh Earnest said.

"Warmbier was reportedly sentenced to 15 years of hard labour, the allegations for which this individual was arrested and imprisoned would not give rise to arrest or imprisonment in the United States, or in just about any other country in the world," he said yesterday.

Warmbier was convicted under an article of the criminal code dealing with subversion, KCNA said.

"In the course of the inquiry, the accused confessed to the serious offence," it said, without elaborating.

The White House accused North Korea of using US citizens for furthering its political agenda.

"Now, despite official claims that US citizens arrested in North Korea are not used for political purposes, it is increasingly clear that the North Korean government seeks to use these US citizens as pawns to pursue a political agenda.

"This underscores the risks associated with travelling to North Korea. And the Department of State strongly recommends against all travel by US citizens to North Korea," Earnest said.
