The United States announced on Monday visa restrictions against “leaders” and “accomplices” of violence in western Cameroon, the scene of a four-year bloody conflict between armed Anglophone groups and the army. The sanctions are aimed at “those who undermine the peaceful resolution of the crisis,” Africa News quotes the US State Department as saying in a statement, without naming those targeted by the ban. The English-speaking minority in Cameroon’s northwest and southwest regions blame the French-speaking majority for marginalizing them, while separatist rebels calling themselves ‘Amba boys’ have said they seek to create an independent state named Ambazonia. International NGOs and the UN regularly accuse both sides of abuses and crimes against humanity in the violence, which has left more than 3,500 people dead and forced more than 700,000 to flee their homes.
