This particular bomb attack, one of four that day, killed 27 people. Survivors and relatives of victims are privately marking the fifth anniversary of the terrorist attacks on London's public transport system. No official events are planned to commemorate the anniversary Wednesday. A spokeswoman for the Department for Culture, Media and Sport said none of the families contacted the agency to ask for an official ceremony. British Prime Minister David Cameron is sending a wreath to a memorial in London's Hyde Park honoring the 52 people killed in the 2005 suicide bombings. The monument consists of 52 steel pillars, one for each of the victims. Suicide bombers set off coordinated explosions in three subway trains and a bus in the British capital on the morning of July 7, 2005, nearly four years after the September 11, 2001 terrorist attacks in the United States.  .
