President Barack Obama signed an executive order today calling for the closure of Guantanamo Bay.
The directive demands that the controversial detention camp in Cuba be shut down within a year.
Yesterday, in one of the first moves of Mr Obama's administration, military trials at the centre were suspended for 120 days while a presidential review is carried out.
In signing the order, Mr Obama honoured a pledge he made before being inaugurated.
He also issued orders reviewing military trials of terror suspects and banning the use of torture.
On the war against terror, Mr Obama said: "We intend to win this fight, but we are going to win it on our terms."
He added that it was the US's ideals that gave it "the strength and moral high ground" to effectively deal with the "unthinking violence" of terrorism.
