On 21 July 2005, a second series of explosions were reported in London, two weeks and some hours after the 7 July 2005 London bombings. Four controlled explosions, of devices considerably less advanced than those of the previous attacks, were carried out at Shepherd's Bush, Warren Street and Oval underground stations, and on a bus in Shoreditch. Even though the attacks on 21 July were less severe than those two weeks earlier, Blair was reported to have said that the bombings in London today were intended "to scare people and to frighten them, to make them anxious and worried". He went on to say how the "police have done their very best, and the security services too, in the situation, and I think we have just got to react calmly and continue with our business as much as possible normal".
