Dubai: An Islamist website reported on Monday that Osama bin Laden warned in the final tape he recorded before being killed by American commandos that there will be no US security without Palestine security.

Addressing directly to US President Barack Obama in an audio message, he said, "America will not be able to dream of security until we live in security in Palestine. It is unfair that you live in peace while our brothers in Gaza live in insecurity."

"Accordingly, and with the will of God, our attacks will continue against you as long as your support for Israel continues" Osama warned.

Earlier on Friday Al-Qaeda confirmed the death of bin Laden but warned that those rejoicing his killing would have their "blood mixed with tears."
