"President Obama moments ago signed an executive order closing the Guantanamo detention facility within a year.
The move makes good on a key Obama campaign promise.
Obama also signed two other orders, reviewing military trials of terror suspects, and banning the harshest interrogation methods.
After signing, Obama said:
"The message we are sending around the world is that the US intends to prosecute the ongoing struggle against violence and terrorism and we are going to do so vigilantly, we are going to do so effectively, and we are going to do so in a manner that is consistent with our values and our ideals ... We intend to win this fight, and we intend to win it on our terms."
