Newly released photos from the US National Archives show the immediate response of Bush administration officials following the September 11, 2001 attacks.
A documentary group had requested the photos under the Freedom of Information Act.
In the photos, then-US President George W. Bush met with senior cabinet members at the President's Emergency Operations Center in the White House.

The attacks that day killed nearly 3,000 people in New York City, Washington and Pennsylvania.
The dramatic events would go on to shape the following decade with two wars fought and a global hunt for militants from al-Qaida.
The attacks led US forces to invade Afghanistan in order to topple the Taliban rulers who had harbored al-Qaida leader Osama bin Laden and Washington began a "war on terror" that ousted Iraq's Saddam Hussein and persists on several fronts to this day.
