Obama after the assassination of Al Qaeda leader: Justice was granted for families of victims of 11 September

The United States has killed al-Qaeda leader Ayman al-Zawahiri in a fearful attack in Afghanistan.

The news was confirmed by US President Joe Biden on Monday in a speech from the White House.

Through a post in Twitter, Obama has indicated that the death of al-Qaeda leader shows it is possible to eliminate terrorism without being at war in Afghanistan.

Meanwhile, he failed to mention the terrorist attack on the 11 September twin towers.

Obama said he hopes that the Al-Qaeda leader's assassination will bring peace to the families of the victims of 11 September, as well as to other people who have suffered at al-Qaeda's hands.

Zawahiri, who just turned 71, had remained a symbol of the group, 11 years after the US killed Osama bin Laden. At one point, he acted as bin Laden's personal physician.

Zawahir was taking refuge in the centre of Kabul to rejoin his family, Biden said, and was killed in what a senior administration official traversed as “a precisely adapted air strike”.

The drone attack was carried out at 21:48 local time Saturday was authorised by Biden after weeks of meetings with his cabinet and key advisers.

Confirmation of the attack took place hours after Taliban rulers in Kabul said a missile attack Sunday against a residential complex in the Afghan capital was carried out with an American threat.

Afghanistan's “Islamic favourability strongly condemns this attack on any pretext”, Taliban spokesman Zubiullah Mujahedid said in a statement, using the official name for the Taliban government.

He denounced the attack as a “open violation of international principles and the Dohas” agreement, referring to the 2020 agreement his group signed with the US, which led to the withdrawal of all American and Allied troops from Afghanistan last August, after almost 20 years of fighting with the Taliban.

The Islamic rebel group took over Afghanistan on 15 August after the US-led foreign troops withdrew and the Western-backed government in Kabul, as well as its security forces, collapsed in the face of the Taliban attack.

The US-led military coalition invaded Afghanistan in October 2001 and toppled the then Taliban government in Kabul to punish him for hosting the al-Qaeda terrorist network. Bin Laden and al-Zahiri survived the international military operation. US special forces later found and killed bin Laden deep inside neighboring Pakistan in May 2011. /abcnews.al/
