US President Barack Obama says US stronger ten years after September 11 attacks

US President Barack Obama said on Saturday the United States was stronger ten years after the September 11, 2001, attacks and highlighted that Americans would "carry on" despite continued threats against their safety.

Marking Sunday's 10th anniversary of the "9/11" attacks on New York, Washington and Pennsylvania, Obama noted that Al-Qaeda's strength had been sapped by relentless US efforts in the decade since the tragedy killed nearly 3,000 people.

"Thanks to the tireless efforts of our military personnel and our intelligence, law enforcement and homeland security professionals, there should be no doubt: today, America is stronger and al Qaeda is on the path to defeat," Obama said in his weekly radio and Internet address.

Obama noted that terror groups would continue to target the United States. "Yes we face a determined foe, and make no mistake - they will keep trying to hit us again. But as we are showing again this weekend, we remain vigilant," he said. "We're doing everything in our power to protect our people, and no matter what comes our way, as a resilient nation, we will carry on."
