The commentator, going by the online name "Assad al-Jihad2" posted Monday 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."
Militant websites regularly post long interviews with al-Jihad2 on the protocols of waging holy war and he is 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.
