On April 18, 2010, Abu Ayyub al-Masri was killed in a joint American and Iraqi operation near Tikrit. The coalition forces believed al-Masri to be wearing a suicide vest and proceeded cautiously. After the lengthy exchange of fire and bombing of the house, the Iraqi troops stormed inside and found two women still alive, one of whom was al-Masri's wife, identified as al-Masri, Abu Omar al-Baghdadi, and al-Baghdadi's son. A suicide vest was found on al-Masri's corpse, according to the Iraqi Army.
