The United Nations Refugee Agency (UNHCR) says it is deeply concerned about the escalating humanitarian crisis in Mozambique's northern Cabo Delgado province, as a recent upsurge in violence by non-state armed groups (NSAGs) continues to force thousands of people to flee to southern districts in search of safety. Since the latest outbreak of violence and attacks against civilians in early February, more than 70,000 women, children and men have been forcibly displaced.
