Remembrance ceremonies have been held across the United States to commemorate the victims of al Qaeda’s attacks on the country this day thirteen years ago.
President Barack Obama spoke at the White House in service for relatives of those killed.
“They sought to do more than bring down buildings or murder our people. They sought to break our spirit and to prove to the world that their power to destroy was greater than our power to persevere and build. But you and America proved them wrong,” Obama said.
In what has become an annual ritual, victims’ relatives recited the names of those killed when New York’s twin towers fell.
A silver bell was also rung to herald moments of silence marking the times when each of the four planes hijacked by Islamist militants crashed.
