Dozens of Syrian parents say their children have gone missing after last weekend’s bomb attack on a convoy of buses near Aleppo.

More than 100 people, including 68 children, were killed in an attack near buses carrying Syrians evacuated from two besieged government-held towns, according to a monitoring group.

In the confusion that followed, children were taken for treatment in areas they were not meant to enter.
