evidence: Fasht Dibal [edit]A dispute arose over Fasht Dibal in 1985 after Bahrain began constructing fortifications on the island. Qatar considered the construction to be a violation of an existing agreement made in 1978.[9] In April 1986, Qatari troops arrived on the island via helicopter and declared it a 'restricted zone'. They seized several Bahraini officials and 29 construction workers hired by the Dutch contracting company Ballast Nedam.[9][11] On 12 May 1986, following protests by the Netherlands and mediation by several GCC member states, Bahrain and Qatar reached a settlement, after which the foreign workers were released. Qatari troops evacuated the island on 15 June.[11] The island was later awarded to Qatar in the aftermath of the 2001 ICJ case.[10]
