More than two decades after the September 11 attacks, the American prison camp at Guantánamo in Cuba still has 34 prisoners.
The Department of Defense said Thursday in Washington after Majid Khan, a detainee from Pakistan, was transferred to the Central American country of Belize.
The government is continuing to work with other countries to responsibly reduce the number of prisoners and eventually close the camp, it said.
The camp is located in Cuba at the Guantánamo Bay Naval Base.
At times almost 800 people were imprisoned there.
The camp was set up under Republican President George W. Bush after the September 11, 2001 terrorist attacks in the United States to hold suspected Islamist terrorists without trial.
Human rights organizations have long called for the closure.
After his release, Kahn announced that he felt like a new person.
Soon he will meet his daughter, who was born after his incarceration, and his wife after 20 years.
He was given a second chance and will make the best of it, Khan said.
He regrets his actions and has tried to make amends for them.
According to Kahn, he was born in Saudi Arabia and grew up mainly in Pakistan and America.
After his return to Pakistan after the September 11 attacks, he was recruited by family members from the Al-Qaeda terrorist militia.
According to the US military, he was involved in an assassination attempt on then-Pakistani President Pervez Musharraf and provided money to an al-Qaeda-affiliated terrorist organization in Indonesia, which used it to finance the 2003 attack on a hotel in Indonesia which killed eleven people.
