Photos of Birmingham DHL fire suggest device could have downed plane

Minworth depot images show strength of incendiary devices thought to be part of Russian sabotage plot

Photographs of the fire caused by a suspected Russian incendiary device at a DHL facility in Birmingham in July have backed up intelligence assessments that the blast was strong enough to have brought down a cargo plane.

One image appears to show when the booby-trapped item, hidden in a massage device, caught fire. A distinctive bright light emerges from the top of a crate of parcels being moved around the site on an electric vehicle.
