The prominent commentator, going by the online name "Assad al-Jihad2," posted on extremist websites a long eulogy for bin Laden and promised to "avenge the killing of the Sheik of Islam."
He also announced that anyone thinking the jihad had ended just had to "wait a little bit."
"The battle between us and international tyranny is long and will not be stopped by the martyrdom of our beloved one, the lion of Islam," said al-Jihad2, whose own online name means lion of jihad. "How many martyrdom seekers have born today?"
Militant websites with links to al-Qaida regularly post long interviews with al-Jihad2 on the protocols of waging holy war. He is also often used to resolve questions of doctrine.
U.S. forces raided bin Laden's heavily guarded compound in a suburb of Pakistan's capital late Sunday, killing him, his son and several associates.
