Guinea-Bissau accused Portugal, the Community of Portuguese Language Countries and a former prime minister of backing a coup bid after a gun battle that claimed at least seven lives.
Gunmen staged a pre-dawn raid on the barracks of an elite army unit near the capital’s airport, sparking a firefight in the latest unrest to blight the chronically unstable country.
Witnesses said the raid had been led by Captain Pansau N’Tchama, the head of a commando unit that assassinated president Joao Bernardo Vieira in 2009.
It was not immediately clear why N’Tchama might have carried out the assault. But the captain is a former associate of the government overthrown in an April 12 coup.
That coup toppled the government of Gomes Junior, interrupting a presidential election between the first and second rounds, which he was leading after the first round.
“The government considers Portugal, the CPLP and Carlos Gomes Junior as the instigators of this attempt at destabilisation,” said a statement read out by Communications Minister Fernando Vaz.
Its aim had been to overthrow the transitional government, undermine the political process, bring Gomes Junior back to power and justify an international “stabilisation” force, the statement added.
In Sunday’s raid, the gunmen launched an assault on the “red beret” barracks at about 4:00 am (0400 GMT).
The soldiers there fought off the attack after about an hour of fighting, forcing the assailants to flee, witnesses said.
N’Tchama is a former member of the “red berets” and returned last week from Portugal, where he had been undergoing military training since July 2009, security sources said.
An AFP journalist at the scene saw the corpses of six attackers. One soldier said that a sentry at the barracks had also been killed by N’Tchama himself.
A military source confirmed the attack but would not say whether there had been any casualties among the troops at the barracks.
In the hours after the raid army vehicles criss-crossed Bissau, although the situation in the capital remained calm.
Troops and police were also out in force at the airport and in the area leading to the capital.
Army chief-of-staff General Antonio Indjai, who led the April coup, visited the barracks after Sunday’s attack, as well as army headquarters in central Bissau.
Following the April coup his junta subsequently handed power to a transitional government led by interim president Manuel Serifo Nhamadjo.
But the ousted African Party for the Independence of Guinea and Cape Verde (PAIGC), which is excluded from the interim government, refused to recognise the new administration.
The country’s instability has allowed drug traffickers operating between South America and Europe to make it a hub for their activities in recent years, with senior military officers believed to be involved in the trafficking.
After the April coup the European Union, the country’s chief trading partner, suspended aid and imposed sanctions on a number of military officers, including Indjai.
At the end of September, interim leader Nhamadjo called on the international community to back the fight against drug-trafficking and help organise elections in 2013.
Since independence from Portugal in 1974, the army and state in the nation of 1.6 million people have remained in constant conflict.
No president has ever completed a full term in office.
