Hundreds of bomb survivors are suffering from lasting injuries

The grants add to �7m already distributed to injured and bereaved people by the London Bombings Relief Charitable Fund.

Those most seriously hurt will get an extra �44,000, bringing their total payout from the fund to �75,000.

The main source of compensation has been �15m from the government's Criminal Injuries Compensation Scheme.

Four suicide bombs were detonated on three tubes and a bus on 7 July, killing 52 commuters and injuring about 700.

The fund was established by London Mayor Ken Livingstone and the Red Cross to distribute donations from the public.

It expects to distribute a further �1.6m before finishing up in the first half of next year.

Bereaved families with two dependent children should now receive about �100,000 in total, a fund spokesman said.

The spokesman said: "The money from the London Bombings Relief Charitable Fund cannot compensate the victims for what they have suffered.

"It is simply intended to help people to rebuild their lives following the tragic events of 7 July, whatever their needs may be."

Government criticised

Victims have demanded more compensation from the government, delivering a 10,000-signature petition to Downing Street in October.

Many said they had no financial help and described the government's compensation scheme as slow, inadequate and insulting.

The Home Office has said it would carry out a review of compensation for victims of attacks after the complaints.
