Pressure cooker bomb

A pressure cooker bomb is an improvised explosive device (IED) created by inserting explosive material into a pressure cooker and attaching a blasting cap into the cover of the cooker.

Pressure cooker bombs have been used in a number of attacks in the 21st century. Among them have been the 2006 Mumbai train bombings, 2010 Stockholm bombings (failed to explode), the 2010 Times Square car bombing attempt (failed to explode), the 2013 Boston Marathon bombing, and the 2017 Manchester Arena bombing.
