Eleven people are now known to have died in Tuesday's failed attempt to overthrow President Umaro Sissoco Embaló, the government of Guinea-Bissau says.

Both soldiers and civilians are reported to be among the dead.

A major investigation has been launched to find the unidentified gunmen.

The army has since been patrolling the streets of the capital.

Shops and banks have been reopening but there are few customers at the markets in Bissau.

The neighbourhood surrounding the main government complex - the site of a five-hour gun battle - is still closed off.

Guinea-Bissau is a hub for cocaine trafficking between Latin America and Europe, leading many to speculate that the coup was the work of drug gangs.
