Guadalcanal [SEP] Civil war
In early 1999, long-simmering tensions between the local Guale people on Guadalcanal and more recent migrants from the neighbouring island of Malaita erupted into violence. The 'Guadalcanal Revolutionary Army', later called Isatabu Freedom Movement (IFM), began terrorising Malaitans in the rural areas of the island in an effort to force them out of their homes. About 20,000 Malaitans fled to the capital and others returned to their home island; Guale residents of Honiara fled. The city became a Malaitan enclave and the Malaita Eagle Force took over government. The Royal Australian Navy and Royal New Zealand Navy deployed vessels to the area to protect the expatriate community resident mostly in Honiara.
