Following the deadly bombing that took place on Sept. 15 in London's Metro, the Islamic State claimed responsibility. 

The bucket bomb that was detonated on a Metro car injured 29 individuals, though none were killed in the attempt. The bomb was hidden in a plastic grocery bag that was placed in a bucket on the Metro during the morning rush.

The Islamic State claimed the attempt was carried out by a disciple, though the implication was that there was more than one person involved in the bombing.

This was the fifth attack on London since the beginning of the year.
