The attack on the Togo football team has significantly raised the profile of the rebel group responsible.
The armed wing of the Front for the Liberation of the Enclave of Cabinda, or FLEC has been waging a long running separatist campaign for the Angolan province, wedged between the two Congolese states.
The group, whose fighters are believed to number fewer than 200, says that locals see few benefits from the province’s abundant oil riches.
The waters off the Cabinda coast provide more than a million barrels per day of oil – half of Angola’s total output – the reason why it has been dubbed “the Kuwait of Africa”.
The Angolan government pledged a greater share of oil revenue for Cabinda in 2006 in exchange for a rebel ceasefire. But division within the FLEC has continued to fuel sporadic violence.
