gelignite

Booby trap, incendiary device, gelignite and rubber bullets are, writes Kennedy, “the vocabulary of a seven-year-old child now.”

In another raid in the same town police found IS uniforms, 150 sticks of gelignite, 100,000 metal balls and a drone camera, a military spokesman said.

"Graham, a compact parcel of Scouse gelignite, doesn't tend to play softies, so his simmering aggression felt all too credible."

Improved equipment, such as the pneumatic drill and gelignite, meant engineers on the second project were able to take make quicker progress and take a more direct line.

When asked if he had planted the gelignite explosives, he replied: "I'm not telling you."
