The disturbing spectacle of Syrian youngsters gathering to watch video footage of people being executed are just one of UN children’s agency UNICEF’s concerns as the conflict enters its fifth year, it said Friday.

Ms Singer told Daniel Johnson that 4.2 million people remain out of reach in conflict zones.
