 However, before this took place, on 20 June 1967 elements of the locally recruited Aden Police mutinied, seizing control over the district in alliance with insurgent forces, staging several ambushes of British troops in the Crater district's streets.Eight British soldiers from a transport unit were attacked and killed by the mutineers, and other British troops were killed in coordinated separate attacks.Three men from the Argylls (its Officer Commanding 'D' company, along with two privates) were killed when a patrol of the Royal Northumberland Fusiliers that they were accompanying was ambushed.
