The footage, which was broadcast by CNN, was taken by a taxi driver who entered Belgium's Zaventem Airport to search for his son, who worked in a food outlet there.

The food outlet was deserted and his son had vanished – it was later reported that he had survived the attacks. But the amateur video shows the carnage from inside the airport's departure lounge as rescue workers try to find and tend to the wounded.

There is debris scattered all over the floor, making it hard for people to wade through to reach the victims. And in one particularly distressing shot, a young baby can be seen standing amid the rubble, crying – while its mother lies somewhere nearby, either dead or seriously injured.
