 In response, the security situation deteriorated with the creation of the socialist Front for the Liberation of Occupied South Yemen (FLOSY) which started to attack the NLF in a bid for power, as well as attacking the British.In January 1967, there were mass riots by NLF and FLOSY supporters in the old Arab quarter of Aden town, which continued until mid February, despite the intervention of British troops.During the period there were many attacks on the troops, and an Aden Airways Douglas DC-3 plane was destroyed in the air with no survivors.
