ISIS second-in-command Abdul Rahman Mustafa al-Qaduli has been killed in bombing raid in Syria, it has been reported.
Al-Qaduli, who was the ISIS finance minister had a $7million bounty on his head was killed earlier this month.
US Defence Secretary Ash Carter confirmed Al-Qaduil's death but refused to go into detail about the mission. He said the death of Al-Qaduli would make it more difficult for ISIS to operate and for the terror organisation to pay their fighters.
The terrorist joined Al Qaeda in 2004 but transferred his allegiance to ISIS following his release from prison in early 2012.
The US Department of Treasury branded al-Qaduli as a 'Specially Designated Global Terrorist' on May 14, 2014.
Carter said US forces are 'systematically eliminating ISIL's cabinet. We killed several key ISIL terrorists this week'.
He said: 'They will be replaced but we will continue to go after their leadership.'
Carter described al-Qaduli as a 'well known terrorist' who was their minister for finance.
He confirmed US forces killed Haji Iman, one of the many aliases used by al-Qaduli.
Carter refused to confirm whether the terrorist was killed in a drone strike or a manned aircraft. He said providing additional details would reduce the effectiveness of future operations.
He said they have taken out the terror organisation's finance chief, affecting their ability to pay their fighters.
He will provide details on the mission along with General Joseph Dunford, chairman of the Joint Chiefs of Staff..
