London police released surveillance photos of the suspects involved in Thursday's attacks on the city's mass transit system.
Also, police are saying that each of the explosives did not fully detonate on the bus and three subway trains. No one died in Thursday's attacks, but they share similarities with the ones two weeks ago that killed 52 people.
