Two separatist guerrilla leaders in Angola's oil-rich Cabinda enclave have been found dead within three weeks, their bodies shot and slashed, Radio Ecclesia reported Tuesday.

The body of Mauricio "Sabata" Lubota, a commander in the rebel Front for the Liberation of the Enclave of Cabinda (FLEC), was found Sunday riddled with bullets and slashed by a knife, the Catholic radio station reported.

Less than three weeks earlier, rebel commander Gabriel Pirilampo's body was discovered in similar condition, the radio added.

A FLEC spokesman told AFP in an unsigned email from the "Cabinda Republic" that they were killed a few months after holding talks with the ruling Popular Movement for the Liberation of Angola (MPLA).

"They were killed by the MPLA armed forces of the regime, as they gave themselves to be known to the MPLA military henchmen and therefore they were easy to be recognised and tracked down," he said.

Angola's government did not immediately reply for comment.

FLEC has been fighting for Cabinda's independence for more than three decades.

Despite a peace deal in 2006, FLEC factions continue to wage low-level attacks in the province, which produces 60 percent of Angola's oil and is separated from the rest of the country by a strip of territory belonging to the Democratic Republic of the Congo.

FLEC's last major attack was staged on January 8 last year, when a bus carrying Togo's football team was ambushed as it entered Angola for the African Cup of Nations. Two people were killed and one person seriously injured.
