After Liberia adopted a new constitution in 1985, Doe was elected president in subsequent elections that were internationally condemned as fraudulent. On November 12, 1985, a failed counter-coup was launched by Thomas Quiwonkpa, whose soldiers briefly occupied the national radio station. Government repression intensified in response, as Doe's troops retaliated by executing members of the Gio and Mano ethnic groups in Nimba County.
