Dancing on the End of a Pin

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?
