London is holding a service at St Paul's Cathedral today to mark the 10th anniversary of the terrorist attacks that killed 52 people on July 7, 2005.
According to BBC, the families of the people who died in the bombing of three Tube trains and a bus will attend the service along with those who were injured.
A minute's silence will be held during the service and on London's transport network.
The attack by four suicide bombers linked to al-Qaeda and carrying rucksacks of explosives was the worst single terrorist attack in London.
