It's a terrible day! 4 bombing attacks happened within an hour in London during rush hour in the morning. Over 50 were killed and nearly 800 were injured. Some dead bodies are supposed to be still lying under the trains in the underground stations.
King's Cross station, Aldgate station, another one underground station and a bus were attacked. Seems that no specific attack target was pinpointed. May God comfort the families of the lost and the injuries. This is my prayer.
