It's only 8pm, but in the bars by the Hospital Roundabout, one of the liveliest nightspots in Bamenda, thoughts are already turning to last orders. "We respect the curfew, we're going to close soon," a waitress warns grumbling clients who would rather drink on into the night as of old, despite a police crackdown triggered by sporadic bombings, arson and killings. Bamenda, a city of about 300,000 people nestled in the mountains of western Cameroon, is the epicentre of an escalating crisis. At its source is resentment among Cameroon's English-speaking minority, angry at perceived discrimination at the hands of the country's francophone majority. Frustration, for some, has spiralled into violence.
