Human Rights Watch on Tuesday accused Cameroon's armed forces of a part in the killing of at least 21 civilians this month in a region where troops are battling anglophone separatists. "Government forces and armed ethnic Fulani" carried out the slaughter in Ngarbuh village, whose victims included 13 children and a pregnant woman, HRW said. The army says there were five civilian deaths, which it said happened when fuel containers exploded in a firefight. gir/js/jpc/ri/jj
