US Air Force deploys B-52 bombers for first time since Cold War-era to target Isis
The US Air Force says it has deployed B-52 bombers to Qatar in the Middle East to take part in the US-led bombing campaign against the Islamic State group.
It is the first time the Cold War-era heavy bombers will be based in the region since the 1991 Gulf War, when they operated from neighbouring Saudi Arabia.
The air force said the B-52s arrived at Qatar's al-Udeid Air Base from Barksdale Air Force Base in Louisiana on Saturday.
The long-range bombers will join a multinational coalition carrying out airstrikes against IS targets in Syria and Iraq.
