A Muslim survivor of the 7/7 London bombings said she is "saddened" about three UK schoolgirls feared to have fled to Syria to join Islamic State.

Sajda Mughal said people had underestimated the power of the internet to radicalise and groom vulnerable youngsters, but "now wider society is picking upon that".

Mrs Mughal was a 22-year-old City high flier who was lucky to escape serious injury in the July 2005 bombings.

Deeply affected by the terror blasts at the hands of fellow Muslims and the rise of Islamophobia, Mrs Mughal quit her job as head of recruitment at an investment bank to work closely with her community.

Now she works with women, largely from ethnic minorities, to help them integrate into society, but also to combat online extremism.

No one has heard from the three east London schoolgirls - Shamima Begum and Amira Abase, both 15, and 16-year-old Kadiza Sultana - more than a week after they left Gatwick Airport.

After collecting her OBE for services to community cohesion and inter-faith dialogue, she said: "Hearing that these young vulnerable girls have gone half-way around the world is saddening and traumatic. My thoughts go out to the family. These are vulnerable girls who have been manipulated with an ideology."

The mother-of-two, from Wood Green, north London, received her award from the Prince of Wales in a ceremony at Buckingham Palace.

Mrs Mughal was on her way to work when 19-year-old Germaine Lindsay detonated his bomb on a Piccadilly line Tube train between King's Cross and Russell Square.

She said: "Having gone through 7/7 myself, I do not want (to see) another 7/7. My work is to try and prevent such an attack. I would not wish what I experienced that day, the trauma, and what I have seen to happen to another person.

"Luckily I was not physically hurt. Had I got on to that first carriage I probably would not be sat here today, because the bomb was on the first carriage. It was only because I was running late.

"What I saw that day, and even with the flashbacks (that I still get), I would not wish it on anyone."

Mrs Mughal is the daughter of Ugandan-Asian parents who escaped Idi Amin. She has been a Londoner since she was a year old.

Helping to tackle online extremism is a way for people to "safeguard their children and to ultimately safeguard society", she added.

She has published a report - Internet Extremism: Working towards a Community Solution - which highlights and explores online radicalisation in the UK and discusses community-based solutions.

Rebecca Donnelly, 36, a former world Thai boxing champion, of Bromley, south east London, collected her MBE for services to community sport through the charity Fight 4 Change (F4CF).

A very nervous Miss Donnelly was asked by Charles if she had been a boxer.

He told her that "it is a brilliant tool for engaging young people, especially the hard-to-reach".

She spends more than 60 hours a week working to help wayward youth, all on a budget of just £80,000 a year.

The charity uses boxing and martial arts as the hook to attract marginalised young people and mentors them to become positive members of society.

Last year F4CF recorded working with 5,120 youngsters in sports development programmes and 291 young people involved in gang intervention schemes.

After collecting her award Miss Donnelly said: "I was quite nervous. I did not think I would be. I was so worried about messing it up and then I saw my twin sister Nichola and nearly had a fit of laughs because I was so nervous. I told her to turn around and not look at me.

"I am really pleased to get this award. The reaction from family and friends has been amazing."
