Indian security 'thwarts Games attacks'

Many potential attacks on the Commonwealth Games in New Delhi have already been thwarted, according to Indian officials who are promising "foolproof" security.

The weekend bombings outside the stadium at an Indian Premier League cricket match in Bangalore which injured at least 10 people have revived international jitters about the safety of those attending the October 3-14 Games.

The blasts rekindled fears aroused by the February bombing at a cafe in Pune, east of Mumbai, which killed 17 people, and the Mumbai attacks which killed more than 170 less than 18 months ago.

But high ranking Indian Games official T.S. Darbari has reassured Australian athletes and challenged suggestions that their visiting family and supporters could be at risk when outside the sporting venues or beyond protection perimeters.

"Delhi is very, very safe (and) secure - not only for the sports people who are coming but also for their families and for the tourists," Darbari told AAP.

Darbari, joint director general of the Organising Committee of the Commonwealth Games 2010, is leading a delegation to Australia accompanying the Queen's baton relay.

He echoed the sentiments from Delhi that Games security measures will be unprecedented.

"I know what the plan is that is being formulated, I can't share the details, but let me tell you it is foolproof."

India's delegation also includes D.R. Kaarthikeyan, a former director of his country's Central Bureau Investigation.

Kaarthikeyan, one of many security experts advising Games officials, says statistics show that nearly all potential attacks are thwarted.

"When something succeeds, you can see 99 have been prevented," he told AAP.

He would not divulge specific measures to protect Delhi from terrorist attacks but did reveal that security agencies have already stopped potential attacks in the host city.

"So many are being rounded up, so many have been detected," Kaarthikeyan said.

"But then they will not be discussed in public. What have been prevented, what have been planned and the stage of plotting itself, that does not come out."

Tourists can expect obvious signs of security in Delhi streets during the Games but most measures will be covert.

"They feel more assured when they see a lot of policemen around and gunmen around, because we cannot take chances," he said.

Kaarthikeyan also said security was so tight in India's major cities that attackers were resorting to small disruptions in rural and regional areas.
