Angolan authorities have expelled 432 illegal foreign nationals, state news agency Angop reported.
According to Angop, the illegal migrants were arrested by the authorities in the Cabinda Province.
They were intercepted in Yema, Massabi, Chiobo and Chingundo border points, Angop said.
Largest exporter
The agency said 428 of the illegal foreigners were from the DR Congo, while the other four were from the Republic of Congo.
With a population of 400,000 people, Angola's Cabinda Province is geographically separated from the rest of the country and borders both DRC and Congo.
It accounts for much of Angola's oil production, which makes the country the largest exporter in Africa.
