British Prime Minister David Cameron led sombre tributes on 7 July as Britain commemorated the 10th anniversary of the 7/7 bombings in London.
It was a time to reflect on the attacks that killed 52 people in London as well as the four bombers, the first suicide bombings by Islamist militants in western Europe.
"Ten years on, this is one of those days when everyone remembers exactly where they were when they heard the news. It's a day when we recall the incredible resolve and resolution of Londoners and the United Kingdom. A day when we remember the threat that we still face. But above all it's a day when we think about the grace and the dignity of the victims' families, for all they've been through, and we honour the memory of those victims and all those who were lost ten years ago today."
In the early hours of 7 July 2005, four young British Muslims travelled to London before detonating homemade bombs hidden in rucksacks on three underground trains and a bus during the morning rush-hour.
Inspired by al Qaeda, they killed themselves and 52 other people and wounded around 700 others. Citizens from Poland, Israel, Australia, France, Italy, Afghanistan, Nigeria, New Zealand and a Vietnamese-American were among the victims.
