Mourners will today mark the tenth anniversary since terrorist attacks in London claimed the lives of 52 people and injured hundreds more.

The country will fall silent to mark the 10th anniversary of the atrocity in which hundreds were injured when four suicide bombers attacked London's transport network.

David Cameron said the Tunisian beach massacre showed the danger remains 10 years on but vowed the nation would not be cowed by violent extremists.

The Prime Minister 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."

Suicide bombers Mohammed Sidique Khan, 30, Shehzad Tanweer, 22, Hasib Hussain, 18, and Jermaine Lindsay, 19, met at Luton station that morning.

They took a train to King's Cross in London, hugged and separated to carry out their deadly missions.

Within three minutes of 8.50am, Tanweer detonated his bomb at Aldgate, Khan set his device off at Edgware Road and Lindsay blew himself up between King's Cross and Russell Square.

Hussain detonated his device on a number 30 bus at Tavistock Square at 9.47am.

Twenty-six died in the bombing at Russell Square on the Piccadilly line, six in the bombing at Edgware Road on the Circle line, seven in the bombing at Aldgate on the Circle line, and 13 in the bombing on the bus at Tavistock Square.

St Albans investment banker Philip Duckworth, 41, described the blast on a Circle Line underground train at Aldgate as a bright white flash.

Mr Duckworth travelled to London from St Albans City Station on the same train as the four bombers, and told the Review he had lain unconscious on the tracks after Shehzad Tanwer detonated his deadly rucksack.

He described hearing the rescuers walk past his lifeless body, believing he was dead.

A fortnight later, another four would-be suicide bombers launched failed attacks on the Tube and a bus, leading to police marksmen killing innocent Brazilian Jean Charles de Menezes.

A national minute's silence will be held today at 11.30am.
