9/11 commemoration in Washington, D.C.
Americans on Thursday marked the 13th anniversary of the September 11, 2001 attacks, as President Barack Obama vowed that the nation would never "give in to fear."
Somber ceremonies of remembrance were held in New York and Washington, against the backdrop of Obama's pledge to "destroy" Islamic State fighters in Iraq and Syria -- a new front in the war on radical Islam begun in earnest 13 years ago.
"As Americans, we draw strength from you, for your love is the ultimate rebuke to the hatred of those who attacked us that bright, blue morning," Obama said to relatives of victims at the Pentagon -- scene of one of the 9/11 strikes. (AFP)
