Muhammad Ajmal Amir Kasab, the lone captured terrorists of the audacious Mumbai terror attack, was trained by Pakistan Marines, an elite unit of the Pakistan Navy.

In its latest issue, 'The Week' quoting Kasab's interrogation report by an intelligence agency said he and nine others who struck Mumbai last November were taught combat techniques by the Pakistan Marines after being extensively trained by the Lashkar-e-Toiba (LeT) at its various camps.

The report said the terrorists underwent crash courses in surveillance, reading topographical maps, sniping positions, urban warfare and kidnapping.

The magazine also said Kasab's interrogators think that the terrorists could in "all possibility" have done a recce of the targets in Mumbai much ahead of the 26/11.

It said that a senior Research and Analysis Wing officer had said that Ismail, the leader of the pack, did the recce with the help of local elements.

Kasab told the interrogators that he and his comrades were taken to sea briefly in the initial stages of the intensive training programme.

"The acclimatisation drills continued for two months in two separate instalments. Nautical miles increased in time. And at a later stage, they were taught the specialised techniques in a 'built up' pool," the magazine said in a statement.
