Al Qaeda leader Ayman al-Zawahiri has been killed by a US airstrike in Afghanistan, US President Joe Biden has confirmed.
Addressing the nation from the balcony off the White House Blue Room, Mr Biden said he authorised the strike which killed the man who was one of the masterminds of the 9/11 terror attacks.
Al-Zawahiri was on the balcony of a safehouse in downtown Kabul when he was killed by two hellfire missiles fired from a drone on Sunday morning.
The FBI had been offering $25m (£20m) for “information leading to the apprehension or conviction” of the 71-year-old, whose death is the biggest blow to al Qaeda since its founder Osama bin Laden was killed by US special forces in 2011.
The operation to kill the al-Qaeda leader was many months in the planning, according to a senior US administration official.
Mr Biden was first briefed about a proposed operation to take out the al Qaeda leader on 1 July this year.
But it was much earlier in the year when intelligence suggested that his wife and children had relocated to Kabul. He and his family were believed until that point to have been in hiding in Pakistan.
The family were located to a safe house where, the US official says, Zawahiri was eventually spotted too.
He was watched for several months and his pattern of life was recorded. He never left the house but did spend time on a balcony where he was eventually killed.
Mr Biden began delivering an address to the nation at 7:30pm in Washington D.C. (12.30am UK time).
A senior official in the Biden administration has said: “Over the weekend, the United States conducted a counterterrorism operation against a significant al Qaeda target in Afghanistan.
“The operation was successful and there were no civilian casualties.”
Mr Biden is speaking from the balcony off the White House Blue Room as he remains in isolation in the residence while he continues to test positive for COVID-19.
Taliban spokesman Zabihullah Mujahid has confirmed that a strike took place and strongly condemned it, calling it a violation of “international principles”.
Speaking on 31 August 2021, after the last US troops left Afghanistan, Mr Biden said the US would not let up on its fight against terrorism in that country or elsewhere.
“We will maintain the fight against terrorism in Afghanistan and other countries,” he said.
“We just don’t need to fight a ground war to do it.”
Previewing the strike that would occur 11 months later, Mr Biden said at the time: “We have what’s called over-the-horizon capabilities, which means we can strike terrorists and targets without American boots on the ground – or very few, if needed.”
Al-Zawahiri helped coordinate the 9/11 attacks in which four passenger aircraft were hijacked and flown into both towers of the World Trade Center in New York, the Pentagon and a field in Pennsylvania.
The terror attack left nearly 3,000 people dead on 11 September 2001.
He was also charged in the US for his alleged roles in the 7 August 1998 bombings of the US embassies in Dar es Salaam in Tanzania and Nairobi in Kenya.
The Egyptian had been bin Laden’s personal doctor before becoming his deputy and eventually his successor.
Al-Zawahiri was reported to be the brains behind some of the group’s grandest ambitions, including the terror group’s unsuccessful efforts to acquire nuclear and biological weapons.
In recent years he presided over al Qaeda at a time of decline, with most of the group’s founding figures dead or in hiding.
