Query: Where did an abortive coup occur in 1993?
Context: A number of assassination attempts against Gaddafi were foiled, and in turn, 1989 saw the security forces raid mosques believed to be centres of counter-revolutionary preaching. In October 1993, elements of the increasingly marginalised army initiated a failed coup in Misrata, while in September 1995, Islamists launched an insurgency in Benghazi, and in July 1996 an anti-Gaddafist football riot broke out in Tripoli. The Revolutionary Committees experienced a resurgence to combat these Islamists.
