(CNN) -- Al Qaeda released a statement on jihadist forums Friday confirming the death of its leader, Osama bin Laden, according to SITE Intelligence Group, which monitors Islamist websites.
The development comes days after U.S. troops killed bin Laden in a raid on a compound in the Pakistani city of Abbottabad.
The statement, translated by SITE, lauded the late militant, threatened to take action against the United States, and urged Pakistanis to "rise up and revolt."
Bin Laden's death will serve as a "curse that chases the Americans and their agents, and goes after them inside and outside their countries," the message said.
"Soon -- with help from Allah -- their happiness will turn into sorrow, and their blood will be mixed with their tears," it said.
The statement said al Qaeda will "continue on the path of jihad, the path walked upon by our leaders ... without hesitation or reluctance."
"We will not deviate from that or change until Allah judges between us and between our enemy with truth. Indeed, He is the best of all judges. Nothing will harm us after that, until we see either victory and success and conquest and empowerment, or we die trying."
It said that Americans "will never enjoy security until our people in Palestine enjoy it."
"The soldiers of Islam, groups and individuals, will continue planning without tiredness or boredom, and without despair or surrender, and without weakness or stagnancy, until they cause the disaster that makes children look like the elderly!"
It urged Pakistanis "to cleanse this shame that has been attached to them by a clique of traitors and thieves" and "from the filth of the Americans who spread corruption in it."
Bin Laden and other militants used the Internet to post messages to their followers before and after al Qaeda's September, 11, 2001 attack on the United States.
