Baghdad (AP) -- The U.S. Military says it's looking into reports that the leader of Al-Qaida in Iraq has been killed.
The chief Iraqi government spokesman also says Iraqi officials have received reports that Abu Ayyub Al-Masri Was killed by Sunni tribesman.
But he says that information has not been confirmed.
Iraqi officials have rushed out similar reports in the past, only to acknowledge later that they were not accurate.
The Iraqi government spokesman says word of Al-Masri's reported death is based on "intelligence information."
U.S. Lieutenant Colonel Christopher Garver says he hopes Al-Masri is dead but says they have to be "very careful" because previous iraqi claims have proven false.
Tribesmen in Anbar Province have been fighting Al-Qaida for weeks and claim to have killed dozens of militants.
Al-Masri took over leadership of the terror network after Abu Musab Al-Zarqawi was killed in a U.S. airstrike last June.
