Aden Emergency
All British forces were withdrawn from Aden by the end of November 1967, despite the ongoing Aden Emergency. Along with the withdrawal from the Persian Gulf, this left bases in Oman as the only UK installations in the Middle East by the mid-seventies. The final installations, the RAF bases at Salalah and on Masirah Island, closed in 1976 following the end of the Dhufar rebellion.
