Jazeera airs tape of new Qaeda leader in Afghanistan

DUBAI (Reuters) - Al Qaeda has appointed a new leader in Afghanistan, al Jazeera television reported on Thursday, broadcasting a statement in which he said support for the group was growing.

"The number of fighters is increasing. The support they receive from Muslims in Afghanistan is almost total", Mustafa Abu al-Yazid said in excerpts aired by the Arabic channel.

He pledged allegiance to al Qaeda leader Osama bin Laden and his deputy Ayman al-Zawahri.

"God bless our two emirs, Sheikh Osama and Sheikh Ayman for globalising the jihad (holy war) ... May both sheikhs, Osama and Ayman, remain a thorn in the side of (U.S. President George W.) Bush."

Abu al-Yazid was not known before and it was the first time that Jazeera is known to have broadcast any of his comments.

It was not clear why al Qaeda decided to appoint him at this time.
