Cameroon's Defence Minister Joseph Beti Assomo, called on all foreign nationals in the country's restive regions, to be cautious after an American missionary died after being shot in the head, amid fighting between armed separatists and soldiers in the northwest on Tuesday this week.

Assomo called on all foreign nationals to immediately inform the military, if they must visit different places in those regions, so that their safety can be assured.

He added that Cameroon's English-speaking northwest and southwest regions, where separatists are fighting for an independent state are dangerous for foreigners.
