North Korea charging American with plotting to topple government

North Korea said Saturday that it is holding a trial for an American citizen who is charged with plotting to overthrow the government.

Kenneth Bae, a Korean-American tourist, is being tried in North Korea’s Supreme Court and could face the death penalty, the Associated Press reported.

The case could complicate further already tenuous relations between the United Sates and North Korea, after Pyongyang has threatened to strike the U.S. with a nuclear weapon.

Bae has been held by police since November, when he arrived in the northeastern city of Rajin with a group of five tourists, according to Reuters.

"In the process of investigation he admitted that he committed crimes aimed to topple the DPRK [Democratic People’s Republic of Korea] with hostility toward it," Pyongyang’s state-run media reported.

South Korean rights workers said that he may have been carrying photographs of homeless North Korean children, and a South Korean newspaper said he may have had footage of defectors being executed, Reuters reported.

In 2009, North Korea held two American television reporters, which led to former President Bill ClintonBill ClintonRobert Siegel leaving NPR's 'All Things Considered' Press: Hillary's doomed bid Beyond Manafort: Both parties deal with pro-Russian Ukrainians MORE traveling to Pyongyang in order to help secure their release.

Tensions between North Korea and the Untied States have ratcheted up in recent weeks after Pyongyang conducted another nuclear test, leading to new sanctions.

North Korea has threatened to attack both South Korea and the United States, and the U.S. military has flown B-2 bombers over South Korea and moved several destroyers in response.
