text: Ex-minister , son killed in Central Africa unrest . Raphael Kopessoua BANGUI 1996-12-06 A former cabinet minister in Central African Republic and his son were abducted from their home and murdered in growing ethnic violence in the capital Bangui , a government minister said on Friday . With violence spiralling out of control , France voiced backing for the elected Bangui government but said its troops based in the former colony under defence pacts would not help it combat army mutineers . " France cannot be involved in the domestic political debate , " President Jacques Chirac told a news conference at the end of a Franco-African summit in Burkina Faso . " French troops may only take part in maintaining order to avoid major abuses and protect foreign communities , " he said . Public Service Minister David Dofara , who is the head of the national Red Cross , told Reuters he had seen the bodies of former interior minister Christophe Grelombe and his son , who was not named . Witnesses said they had been seized by troops loyal to President Ange-Felix Patasse at dawn on Thursday when they clashed with soldiers staging a mutiny since November 16 . Grelombe is from the Yakoma tribe to which most of the rebel soldiers belong . The uprising began over pay demands but has turned into a campaign to topple Patasse , sparking ethnic violence and dividing the capital . The former minister and his son had been taken from their home close to the presidential palace , which is guarded by loyalist soldiers backed by French troops based in Bangui . The bodies were found on Thursday in an open field about two km ( one mile ) further away , said Dofora and other witnesses . The men were seized as loyalist forces and French troops fought gunbattles with mutineers who fired rockets into the city centre . A French-owned hotel was slightly damaged . Yakomas are hounded in stronghold districts of Patasse 's Baya people while other tribes have fled areas in rebel hands . Roadblocks have been erected in city districts while central Bangui , which is patrolled by French troops with tanks , is deserted . Shops and businesses have remained shut this week . The Franco-African summit decided to send a mission Bangui to seek ways of containing the mutiny and a threat of civil war . Chirac said Burkina Faso President Blaise Compaore would visit Bangui " in the coming hours " with the heads of state of Gabon , Mali and Chad to try and establish dialogue between authorities and rebels . The mutiny forced Patasse to miss the summit . His spokesman had predicted the meeting to send an assessment mission . Patasse , who won Central Africa 's first multi-party elections , refuses to resign . Church-led meadiation attempts hit deadlock over rebel demands for his departure . Soldiers staged mutinies in April and May , with French troops stepping in with tanks and helicopters to quell the more serious second uprising . Patasse offered concessions and amnesty to rebels before the May rebellion ended after rebels looted the city centre . Rebels accuse Patasse of tribalism and of arming his civilian supporters and hired guns from Sudan and Chad . Mutineers have vowed to disarm all civilians and to chase out the foreign forces knwon as Codos . Hospital sources and witnesses said about 10 people were known to have been killed in the more than two weeks of fighting , including two rebels killed in Thursday 's clashes . An undetermined number of people are reported to have been abducted and killed outside the town by tribal vigilante groups . In Thursday 's fighting , French troops fired back as mutineers trying to break out of their strongholds rained mortar shells on the city centre .
