UN Secretary-General Antonio Guterres says he is alarmed at reports that children may constitute a large part of the force recruited and used by al-Shabab Islamic extremists in Somalia.
Guterres said it's estimated over half its force are children, noting that at least 60 per cent of al-Shabab "elements" captured in Somalia's semi-autonomous Puntland region in March 2016 were youngsters.
In a report to the UN Security Council circulated this week, he said children were used in combat, with 9-year-olds reportedly taught to use weapons and sent to front lines.
