A HERO doctor who treated victims of the July 7 bomb blasts was in London again when terrorists struck yesterday.

Mohib Khan, 60, a surgeon based at Huddersfield Royal Infirmary, was chairing a meeting at the British Medical Association headquarters.

He said today that he had immediately gone to offer his help at nearby Warren Street Tube station, one of the targets of the latest attack.

Mr Khan, a urology specialist with 35 years' experience, told of the ``chilling" moment when he heard of the new bombs.

The attacks came hours after Mr Khan attended a memorial service at the BMA for victims of the suicide bombings on July 7.

He had joined hundreds of people for the multi-faith service.

A TERROR expert said the apparent failure to detonate some of the London devices yesterday would give police a huge forensic advantage.

Prof Paul Rogers, of Huddersfield, also said the second wave of attacks on London was an "ominous" development. It could indicate there was least one other terror cell in Britain with links to the July 7 London killers.

Prof Rogers, who lectures at Bradford University, said: "The level of forensic evidence will be extremely high.

"Police will have the devices and much can be done to them in terms of fingerprinting, DNA, the origin of the detonators and where the bags were bought.

"If this was a series of dummies deliberately timed to cause mass panic, then it puts the people responsible at considerable risk of being found."

He added: "The one ominous thing is that this appears to be a group of a similar nature to the July 7 bombers. It implies there might be another cell primed and ready to attack."

KIRKLEES councillor Mehboob Khan has praised the courage and determination of Londoners after yesterday's bombs.

The Birkby ward councillor was in the capital for a Westminster meeting with MPs and community leaders - ironically to discuss a report he had prepared on tackling terrorism.

And, like thousands of others, he was forced to walk as rail stations were shut down during the alert.
