U.S. President Donald Trump announced Wednesday that three American detainees have been released from North Korea and are returning home with Secretary of State Mike Pompeo.

Trump tweeted "I am pleased to inform you that Secretary of State Mike Pompeo is in the air and on his way back from North Korea with the three wonderful gentlemen that everyone is looking so forward to meeting," adding that they seem to be in good health.

Trump also said that Pompeo and the detainees will be arriving at Andrews Air Force Base at 2 a.m. Thursday U.S. time, adding he will be there to greet them.

The three men -- Kim Hak-song, Tony Kim and Kim Dong-chul -- were detained in North Korea on charges of espionage or "hostile acts" against the regime.

In addition, Trump said that Pompeo had a good meeting with North Korean leader Kim Jon-un during his trip, and the date and venue of the Washington-Pyongyang summit have been set.
