This distinction seems rather superfluous:
Al-Banna has been accused of carrying out one of Iraq’s deadliest suicide bombing — the February 28 attack in Hillah that killed 125 people.
But the Jordanian government and al-Banna’s family said he carried out a different suicide bombing in Iraq in which he was killed. The terrorist group al Qaeda in Iraq claimed responsibility for the Hillah bombing.
I mean, does this affect some sort of over/under betting or what?
