Numerous children have gone missing amid the chaos at Kabul airport, German news agency dpa reports.
One family from Kabul has been caring for a lost six-year-old boy they found caught in barbed wire at the airport, Afghan television network Ariana reported. The family has been unable to locate the child's parents despite their best efforts.
The boy told the network his father was trampled in the crowd, and he has not seen his parents since then.
According to local journalists, people have been posting photos of missing children at the airport.
