Members of Guinea-Bissau’s unruly armed forces have blotted the military’s record again with another attack against the country’s political institutions. Early on Sunday, Nov. 23, renegade soldiers, their faces hooded, sprayed the Bissau residence of President Joao Bernardo “Nino” Vieira with machine-gun and rocket-propelled grenade fire. The president survived unhurt this latest apparent attempt to topple him.
