Guinea-Bissau has launched a major investigation into a foiled attempt to overthrow President Umaro Sissoco Embalo, who survived a gun attack on Tuesday in the uprising the government says claimed 11 lives. Al Jazeera reports that the Capital, Bissau, appeared calm on Wednesday as shops and banks reopened, but soldiers were patrolling the streets and also blocked access to the Palace of Government complex where the attack took place. Guinea-Bissau, an impoverished coastal state of approximately two million people lying south of Senegal, has suffered four military coups since independence from Portugal in 1974, its most recent being in 2012.
