A series of coup attempts (in 1980, 1983, and 1988) by Nasir supporters and business interests tried to topple the government without success. While the first two attempts met with little success, the 1988 coup attempt involved a roughly 80 strong mercenary force of the PLOTE who seized the airport and caused Maumoon to flee from house to house until the intervention of 1,600 Indian troops airlifted into Malé restored order.
