A survivor of the 7/7 terror attack has been reunited with a police officer who saved her life.

Gill Hicks, who lost both legs below the knee in the atrocity almost 10 years ago, broke down in tears as she hugged Pc Andrew Maxwell outside Kings Cross station.

Pc Maxwell used a makeshift stretcher to carry her out of a Tube tunnel so she could receive emergency medical treatment.

Ms Hicks had been on board the train that Jermaine Lindsay, 19, devastatingly blew up between the station and Russell Square.

She helped to launch a walk by faith leaders promoting religious unity ahead of the anniversary of the attacks.

Ms Hicks presented Pc Maxwell with a higher commendation for "extreme courage" in 2006.

She has described how she formed an "indescribable bond" with her rescuers and he is one of her best friends.

Imam Qari Asim, of Leeds's largest mosque Makkah Masjid, the Rev Bertrand Olivier, vicar of All-Hallows-by-the-Tower in the City of London, and Rabbi Laura Janner-Klausner, from Movement for Reform Judaism, led a procession with a floral tribute reading "Together" for the short walk to Tavistock Square, where a London bus was blown up in the attacks.

Mayor Boris Johnson, Labour's Tessa Jowell, Sadiq Khan and Zac Goldsmith, the walk was part of an initiative calling on people in London to "walk together" on the 7/7 anniversary tomorrow by finishing their morning bus or Underground commute one stop early and walking the last few minutes.

Arriving in Tavistock Square, they laid the wreath under a tree after praying together.

Imam Asim said it was important to send out a message of solidarity with against terrorists.

"They are deluded, poisonous individuals and groups of people who want to bring chaos and mayhem to our country and abroad," he said during the walk.

"Terrorists are recruiting young individuals from the Muslim community and as a result it is extremely important for Muslims to stand up and say no to hatred. An attack on British soil or abroad is an attack on all of us."
