The Lashkar-e-Tayiba [Images], which was responsible for the Mumbai terror attacks [Images], goes to extreme lengths to conceal the identity of terrorists while carrying out an attack in India, according to Intelligence Bureau sources.

The interrogation conducted on Ajmal Kasab [Images], Fahim Ansari and Sabahuddin have helped the IB piece together details of the things the LeT does to ensure that the identity of the terrorists is concealed at all times.

An IB source told rediff.com that extreme caution is taken while training terrorists and the levels of security are such that none of the security agencies are able to get a wind of what is happening.

The fidayeens are trained in an area which is at least 20 kilometres away from a populated area. Moreover there should be no army camp or a police station anywhere in a 30-km radius.

While earmarking the area, the LeT ensures that there is enough land to train at least 50 men in shooting and physical training. Apart from this the LeT also ensures that there is a medical facility close by.

The LeT takes a lot of precaution in ensuring that the location is kept a secret. Only the top commander and his second in command apart from the trainers are aware of the location. What is interesting is that once the training programme is completed then the place is not used for at least another year and all traces of the camp are immediately wiped out.

Further the LeT also ensures that the area has several exit points. Once training for the day is complete no one is allowed to hang on there and all trainees return to base camp.

The trainees too are strictly vetted before being admitted. Also care is taken to ensure that the trainees don't know each other. This is done to ensure that there is no bonding between them.
