AN Angolan army helicopter crashed at the weekend in central Angola, killing five of its 13 passengers, most of them military personnel, the Portuguese news agency Lusa said on Monday. A military official interviewed by the agency said the fate of the eight other passengers aboard the Russian-built helicopter that crashed on Saturday was unknown. The aircraft crashed in Balombo, in the central west province of Benguela, as it was carrying merchandise and money to pay salaries of troops stationed in the region. The official, who asked not to be named, said the helicopter was old and may have crashed because it was overloaded. – AFP
