The US has killed the leader of al-Qaeda, Ayman al-Zawahiri, in a drone strike in Afghanistan, President Joe Biden has confirmed.
He was killed in a counter-terrorism operation carried out by the CIA in the Afghan capital of Kabul on Sunday.
He and Osama Bin Laden plotted the 9/11 attacks together, and he was one of America’s “most wanted terrorists”.
Mr Biden said Zawahiri had “carved a trail of murder and violence against American citizens”.
“Since the United States delivered justice to bin Laden 11 years ago, Zawahiri has been a leader of al-Qaeda,” Mr Biden said. “From hiding, he co-ordinated al-Qaeda’s branches and all around the world, including setting priorities for providing operational guidance and calling for and inspired attacks against US targets.”
“Now justice has been delivered and this terrorist leader is no more,” he added.
Zawahiri took over al-Qaeda after the death of Bin Laden in 2011.
Officials said Zawahiri was on the balcony of a safe house when the drone fired two missiles at him.
Other family members were present, but they were unharmed and only Zawahiri was killed in the attack, they added.
Mr Biden said he had given the final approval for the “precision strike” on the 71-year-old Egyptian after months of planning.
His killing will bring closure to families of the nearly 3,000 victims of the 2001 attacks, Mr Biden added.
“No matter how long it takes, no matter where you hide, if you are a threat to our people, the United States will find you and take you out,” said Mr Biden, adding that “we shall never waver from defending our nation and its people”.
Mr Biden said Zawahiri had also masterminded other acts of violence, including the suicide bombing of the USS Cole naval destroyer in Aden in October 2000 which killed 17 US sailors, and the 1998 attacks on the US embassies in Kenya and Tanzania, in which 223 people died.
He insisted that Afghanistan would never again become a safe haven for terrorists.
A Taliban spokesman described the US operation as a clear violation of international principles – but did not mention Zawahiri.
“Such actions are a repetition of the failed experiences of the past 20 years and are against the interests of the United States of America, Afghanistan and the region,” the spokesman added.
However, US officials maintained that the operation had had a legal basis.
The killing of Zawahiri comes nearly a year after US troops completed their withdrawal from Afghanistan on the orders of Mr Biden, bringing an end to a 20-year military presence there.
