Aid agency Save the Children says Islamist militants are beheading children as young as 11 in Mozambique’s northern province of Cabo Delgado. The BBC’s Newsday programme reports that more than 2,500 people have been killed and 700,000 have fled their homes since an Islamist insurgency began in 2017. The militants are linked to the Islamic State (IS) group. In its report, Save the Children said it had spoken to displaced families who reported gruesome scenes in the gas-rich province. The United Nations special rapporteur on extra-judicial executions described the militants’ actions as “cruel beyond words”.
