Events across London are being held to mark the anniversary of the terrorist suicide bombings on 7th July 2005.

They include a national minute’s silence at 11.30 am.

The period of quiet will take place during a service at St Paul’s Cathedral – attended by the Duke of York – and will be observed across the capital’s public transport network.

Survivors, relatives of the dead and members of the emergency services have been invited to the event.

Announcements will be halted and bus drivers asked to bring vehicles to a stop if they can do so safely.

Tube services will run as normal but passengers will be asked to observe the silence and announcements will be halted for the duration, Transport for London said.

Wreaths will be laid beforehand at the permanent Hyde Park memorial, where a second service, to be attended by the Duke of Cambridge, will take place later, featuring music, a series of readings and the laying of flowers.

Members of the emergency services and a 7/7 survivor recall the terrorist attack on London in 2005, painting a timeline of events as they happened.

A total of 56 people died, including 52 civilians and the four bombers. And more than 700 people were injured.

Prime Minister David Cameron said:

Today the country comes together to remember the victims of one of the deadliest terrorist atrocities on mainland Britain.

Ten years on from the 7/7 London attacks, the threat from terrorism continues to be as real as it is deadly – the murder of 30 innocent Britons whilst holidaying in Tunisia is a brutal reminder of that fact. But we will never be cowed by terrorism.

We will keep on doing all that we can to keep the British public safe, protecting vulnerable young minds from others’ extremist beliefs and promoting the shared values of tolerance, love and respect that make Britain so great.

Andrew Parker, the head of MI5, said the ‘continuing fact’ that some British citizens are prepared to target their own country presents a ‘serious societal and security challenge.’

He described the ‘disgusting’ murders 10 years ago as an ‘enduring reminder’ of what his organisation ‘is striving every day to prevent.’
