Two vintage World War Two-era planes have collided and crashed at an air show in the US state of Texas, killing six people.

Footage shows the aircraft striking each other at a low altitude, breaking one of the aircraft in half. A fireball can be seen as it hits the ground.

The planes – one of them a Boeing B-17 Flying Fortress – were taking part in a commemorative air show near Dallas.

Firefighters said there were no injuries among people on the ground.
