Duncan Fletcher believes the England players who have signed up for the Indian Premier League should be concerned about their safety.
The former England coach insists that has found security far more lax in India than anywhere else on the subcontinent.
And following the attack in Lahore - where several members of the Sri Lanka squad were injured and six police officers and two civilians were killed - Fletcher believes England's players need to think again about taking part in the IPL.
Kevin Pietersen and Andrew Flintoff are among the 11 England players who have been bought by sides in the IPL for this year's competition.
And Fletcher said in his column for The Guardian: "If I were one of the England guys who signed up for the Indian Premier League, I would be concerned.
"Less than four years ago I was part of the England tour party to Pakistan that came in for criticism from sections of the media for going overboard on security.
"But if yesterday's events in Lahore showed us anything, it's that you can never be too careful.
"There were times on that tour of Pakistan when the security was at a presidential level - with the exception of Karachi, they cleared roads for us on the way to stadiums and lined them with armed guards.
"India is different. The traffic is often so bad in the big cities where a lot of the cricket is played that the coach can move along only slowly at times, which turns it into a sitting duck for terrorists."
And Fletcher believes that it would be easy for terrorists to launch an attack.
He added: "There's nothing stopping a tuk-tuk pulling up alongside and detonating a bomb. I would be very nervous because that kind of attack is much easier to carry out in India - and these guys can attack when they like.
"I don't want to sound too melodramatic but these terrorists operate as if they are in a war."
