President Obama and wife Michelle mark 9/11 anniversary at White House
U.S. President Barack Obama and his wife Michelle have marked the 13th anniversary of the 9/11 terror attacks at the White House.
They were joined by Vice President Joe Biden as well as other politicians, dignitaries and victims' relatives.
Other similar memorials were held in New York, Washington and Pennsylvania.
Nearly 3,000 people killed in al Qaeda's attack on the United States 13 years ago on Sept. 11.
Last night President Obama announced tougher action against ISIS militants in Iraq.
The new action will for the first time attack militants in Syria.
Meanwhile the struggle against Isis in Syria lies in tatters after the leaders of one of the biggest rebel groups were wiped out by a suspected suicide bomb.
The blast devastated a meeting of Ahrar al-Sham’s senior staff on Wednesday, killing at least 50 people, including the group’s highly influential commander, Hassan Aboud.
The news came as John Kerry arrived in Baghdad on Wednesday to discuss the United States’ desire to build a military, political and financial coalition of nations to defeat Isis, which calls itself Islamic State, with the newly appointed Iraqi government in the capital.
Ahrar al-Sham has been the largest and strongest Islamist group fighting Isis – despite sharing similar salafist views – and has shown more moderate colours in recent months, causing particular distress to the rebels.
The meeting was taking place in an underground bunker known as “Base Zero”, in the town of Ram Hamdan, close to Idlib in north-western Syria. The bunker also housed a munitions store, raising both the possibility of a carefully planned operation or even a tragic accident.
