A car explosion – just metres away from where a British tourist tackled a suspected knifeman to the ground – has shaken Amsterdam’s central Dam Square.

Footage shows a vehicle engulfed in flames in front of the Royal Palace as police clear the area of people.

“We suspect that the driver caused the fire himself. In this case, intent is taken into account. The driver was injured,” the police said. Images show the victim on fire, with officers who rushed to the scene spraying him with a foam extinguisher.
