Those responsible for the 9/11 terrorist attack, which killed nearly 3,000 people in the US, are still plotting and planning another attack on the United States, a top American military official said.
"The people behind the 9/11 attacks are planning and plotting other attacks. Qaida and its extremist allies would like nothing better than to strike us again," Chairman of the Joint Chiefs of Staff Admiral Michael Mullen said at a September 11th Commemoration Ceremony at the Pentagon.
"Our grief is real and it is warranted. But we look upon this day not only with sorrow, but also with hope for the future that those we honour wanted us to have, and gratitude for the life they wanted us to live," Mullen said.
"Let us face that future with the same resolve our men and women in uniform exhibit, the same courage with which they serve and struggle to ensure another day like that day never happens again," he said.
"America has sent her armed forces forward with that task. In harm's way you have deployed them and in harm's way they stand for you and for each other," Mullen said.
