Rahman, who is from Libya, was killed on August 22 in Pakistan’s northern Waziristan region, according to a senior US official, who would not divulge details of the death.
Local Pakistani officials told the AFP news agency last week that a US drone attack on a vehicle in Waziristan killed at least four people on August 22. It remains unclear if the two incidents were connected.
The death of Rahman, who had a one million dollar bounty on his head, will be a blow to Al-Qaeda.
The US official told the AFP news agency that Rahman “had multiple responsibilities in the organisation and will be very difficult to replace.”
Rahman’s death is another success for President Barack Obama, who has committed to wiping out Al-Qaeda’s terrorist network, particularly in northern Pakistan from where the group is thought to operate.
Former leader Osama Bin Laden was killed in a house in Pakistan on May 2 in a seige by US Navy Seals.
Americans are soon to commemorate those who died in Al-Qaeda’s attack on 11 September 2001, which killed nearly 3,000 people in New York and Washington.
