The North Korean government has announced it will prosecute American Matthew Miller who is being held by that country's government for "hostile acts."

In a statement released on Sunday, the North Korean government said that it will try Miller next week, according to The Telegraph, which quoted North Korea's state-run media agency.

"The Supreme Court of the Democratic People's Republic of Korea (North Korea) decided to hold on Sept. 14 a court trial on American Matthew Todd Miller, now in custody according to the indictment of a relevant institution," the statement said.

Miller has been held by the North Korean government since April, when he arrived and tore his tourist visa apart and asked for asylum, according to The New York Times. Pyongyang has accused him of unruly behavior and "hostile acts" against North Korea.

However, he is not the only American currently held by the government of the so-called Hermit Kingdom. Two other Americans, Kenneth Bae and Jeffrey Edward Fowle, are both held by the North Korean government. Bae has been sentenced to 15 years of hard labor for allegedly trying to overthrow the North Korean government. Fowler was tried for "hostile acts."

In an interview with The Associated Press, the three men asked the U.S. government to send envoys to plead their case. Bae, who has been held since 2012, said he did not know he broke the law until his trial and that it lasted only an hour.

The U.S., according to The New York Times, had offered to send Ambassador Robert King, who is in charge of human rights in North Korea. However, Pyongyang refused. The U.S. government has not provided many details on how it will proceed.

"The safety and security of American citizens, including, certainly, those who were detained overseas as an utmost priority to the United States and to Secretary Kerry. This is an issue that is certainly on the forefront of our minds. We have offered in the past to send Ambassador Bob King there. A trip was canceled twice. We're going to leave no stone unturned in this case, and we certainly have means of communicating. But I don't have any additional updates," State Department spokeswoman Jen Psaki said during a Sept. 3 press briefing.
