The self-described leader of an al-Qaida front group has called for continued jihad against Iraq's American "occupiers" in the wake of the March 7 election that he claimed was boycotted by most Sunni Arabs, according to an audio tape posted Tuesday on militant Web sites.In the 24-minute tape, Abu Omar al-Baghdadi said the parliamentary election and its results meant nothing for the mujahideen, or holy fighters, and that the next government would be no different from the previous one. "We announce that the elections outcome means nothing to us ... we will continue chasing the (American) occupier and his agents until we purify the land from their filth," he said in the tape.
