A twin-engine plane slammed into a mountain during bad weather in Angola's central highlands Saturday, killing at least 11 people, state media reported.

Angolan National Radio said there were no survivors in the Beechcraft-200 crash, which occurred just before 8 a.m. local time. State news agency Angop quoted civil aviation officials as saying 12 people were killed.

The aircraft crashed near Huambo, a city about 320 miles southeast of the capital, Luanda, media said.

An army team based nearby reached the crash site and reported that nobody had survived, according to the radio report.

The twin-propeller plane, owned by private airline Gira Globo, had tried to land a two local airports during rain and fog before it crashed, the reports said.

The Beechcraft 200 can carry up to 16 people.

Portugal's national news agency Lusa said two Portuguese businessmen died in the accident.

Angolan Transport Minister Andre Luis Brandao ordered an inquiry into the cause of the crash, Angop said.
