Dubai, May 6, (PTI): Al-Qaeda today confirmed the death of its chief Osama bin Laden, five days after the dreaded terrorist was killed by American commandos in Pakistan's Abbottabad town, warning that his blood would not be ''wasted'' and attacks against the US and it allies would continue.

The confirmation came in a statement posted by the terror network on jihadist websites, according to the US monitoring group SITE.

In the statement, al-Qaeda warned that bin Laden's blood would not be "wasted" and attacks on the US and its allies would continue.

54-year-old bin Laden was killed in a unilateral operation by special US forces in the Pakistani garrison town of Abbottabad near Islamabad early Monday.

"We in al-Qaeda organisation pledge to Allah the almighty and ask his help, support and steadfastness to continue on the path of jihad, the path walked upon by our leaders, and on top of them, Sheikh Osama," SITE said, quoting the statement.

The terror group described itself as a "curse" on America, vowed bloodshed and asked Pakistan to rise up in revolt.

"Soon, God willing, their (the US') happiness will turn to sadness. Their blood will be mingled with their tears," the statement said.

"We call upon our Muslim people in Pakistan, on whose land Sheikh Osama was killed, to rise up and revolt to cleanse this shame that has been attached to them by a clique of traitors and thieves ... and in general to cleanse their country from the filth of the Americans who spread corruption in it," the statement said.
