The M62 coach bombing, sometimes referred to as the M62 Massacre, occurred on 4 February 1974 on the M62 motorway in northern England, when a 25-pound (11 kg) Provisional Irish Republican Army (IRA) bomb hidden inside the luggage locker of a coach carrying off-duty British Armed Forces personnel and their family members exploded, killing twelve people and injuring thirty-eight others aboard the vehicle.
