A survivor of London's 7/7 bombings had an emotional reunion with the police officer who saved her life when she unexpectedly came across him at King's Cross station in London.

Gill Hicks had to have both her legs amputated after she suffered horrific injuries in the attack on a Piccadilly line train between King's Cross and Russell Square Tube stations and was pulled from the wreckage by PC Andy Maxwell.

When he heard Hicks was going to be at King's Cross taking part in a peace walk to honour the 52 people who died in the bombings, he decided to surprise her. The pair shared a tight embrace and Hicks was overcome with tears and emotion at seeing Maxwell again.

To mark the 10th anniversary of the bombings, faith leaders went on a walk from King's Cross station to Tavistock Square, where the bus bomb took place, to promote peace.

"None of the religions condone violence and it is extremely important that religious leaders stand together against hatred and extremism and today by walking together, talking together we are sending out a very strong message to extremists and extremist sympathisers that their actions can never be condoned by any faith and we will not tolerate and accept their kind of behaviour," said Imam Qari Asim, from the Makkah Masjid, Leeds' largest mosque.

He was joined by a Christian reverend and Jewish rabbi as they carried a floral tribute spelling the word "Together".

He said: "We faith leaders believe that Britain is a multi-faith, multi-ethnic, multicultural society and by walking together we are sending out a very strong message that this is what we are proud of and this is what Britain is today."
