Jabr died in the Battle of Sirte. On 20 October 2011, Al Jazeera reported that Jabr was killed in Sirte. He was in a car convoy with Gaddafi trying to flee from the Siege of Sirte. After the convoy was attacked by NATO aircraft he sought shelter from shrapnel in drain pipes with Gaddafi. NTC fighters captured him and Gaddafi. Yunis Jabr was with a group of Gaddafi loyalists, when a guard saw a group of rebels approaching them, off in the distance. He then threw a grenade at them. However, the grenade then bounced off a concrete wall, and landed back in front of them. The guard then attempted to pick the grenade up, but when he did so, it exploded. The detonation killed the guard and, according to witnesses, fatally injured Abu-Bakr Yunis Jabr. He reportedly died on his way to a hospital. Al Jazeera also aired footage of his body being driven away in an ambulance.
