Senior Afghan al-Qaeda leader 'killed in Pakistan'
Al-Qaeda's number three leader and Afghan operations chief, Mustafa Abu al-Yazid, has been killed, reports say.
Mr Yazid, also known as Sheikh Said al-Masri, died along with his wife and three children, Islamist websites said, quoting a statement from al-Qaeda.
US officials say they believe he was killed recently in the tribal areas of Pakistan in an American drone attack.
Previous reports of his death have been wrong, but this is the first time al-Qaeda has acknowledged such claims.
The White House said it welcomed the news, adding that Mr Yazid's death was "unquestionably a severe blow" to al-Qaeda.
Spokesman Robert Gibbs said Mr Yazid was one of the biggest targets to be killed or captured in recent years.
American officials often refer to the Egyptian-born militant as the main conduit to leader Osama Bin Laden.
As al-Qaeda's operational commander in Afghanistan, he is believed to have had a hand in everything from finances to operational planning.'Severe curse'
A US official, speaking on condition of anonymity, said there was "strong reason" to believe that Mr Yazid was killed in Pakistan's tribal areas in the past two weeks.
US monitoring groups said a message from al-Qaeda posted on Islamist forums on 31 May said the militant's wife, three of his daughters, his granddaughter, and other men, women, and children, were killed.
PROFILE: MUSTAFA ABU AL-YAZID
- Alleged founder member of al-Qaeda
- Al-Qaeda's "Number Three" and the organisation's leader in Afghanistan
- Jailed for three years for alleged links to the assassination of Egyptian President Anwar Sadat in 1981
- Linked to the 9/11 attacks of 2001
The message translated by the SITE group, which monitors Islamist websites, did not give any details about the circumstances of his reported death, other than to speak of his "martyrdom".
"His death will only be a severe curse by his life upon the infidels. The response is near. That is sufficient," said the message translated by SITE.
Mr Yazid is thought to have climbed to the number three position in al-Qaeda in 2007, when his predecessor, Abu Ubaida al-Masri, died of hepatitis in Pakistan.
He is reported to have managed the finances for the 11 September 2001 attacks in New York and Washington.
In a rare interview with Pakistan's Geo TV in 2008, he said al-Qaeda was "properly involved" in those attacks, as well as the 1998 attacks on US embassies in Kenya and Tanzania.
He also denounced the Pakistani government for fighting Islamic militants, justified suicide attacks, and predicted victory for Taliban and al-Qaeda forces in Afghanistan.
He is believed to have been jailed in Egypt in 1982 in connection with the assassination of Egypt's then-President Anwar Sadat.
Mr Yazid's last public statement was released on 4 May, eulogising the two top al-Qaeda leaders in Iraq - Abu Omar al-Baghdadi and Abu Ayub al-Masri - who were killed in April.
