Blast bomb
Blast bomb is a term used in Northern Ireland for a type of improvised explosive device. More specifically, these devices are usually a form of homemade grenade, which is thrown at a target. These devices have been used in a number of public order situations, and in attacks on the Royal Ulster Constabulary, its successor Police Service of Northern Ireland and British Army. A police officer was killed by a blast bomb in Northern Ireland during The Troubles by loyalists.
A similar type of device, also common in Northern Ireland, is the pipe bomb.
