Militants have forced 570,000 people to flee their homes in Mozambique’s northern Cabo Delgado province, President Filipe Nyusi said on Wednesday, vowing to defeat insurgents who stepped up attacks since pledging loyalty to Islamic State last year. Reuters reports that fighters have been taking on the army and seizing entire towns in recent months in the province, home to gas developments worth some $60 billion but Nyusi said Mozambique had received offers “from all corners of the world” to help it fight terrorism. Nathan Sales, the Coordinator for Counterterrorism at the US State Department, meanwhile said last week that the insurgents in northern Mozambique belonged to a “committed” affiliate of Islamic State and should be seen as a global terrorism threat.
