Were there more than 10 terrorists involved in the 26/11 siege of Mumbai?

JK Dutt, who was the then NSG chief, says it cannot be ruled out. Speaking to Barkha Dutt on 'We the People' Dutt said more than 10 men from Pakistan may have entered India.

JK Dutt said that he believed it couldn't be ruled out that there were more than ten terrorists behind the siege of Mumbai. He explained that they were told that there were 10 AK 47s and so they believed that there were ten men in the hotel. But there could have been more who entered India around the same time.
 
Excerpts from the interview:

JK Dutt: When I had contacted the senior official in Delhi to find out how many terrorists we had to account for, I was told that I had to account for 10 AK-47s. Now we had nine; two had been got by the local police, two at Oberoi, Nariman House and three over here. It was only three hours later when our NSG dog went around looking for unexploded grenades or explosives that it smelt out sniffed out the tenth weapon that was lying under a lot of soot and carbon because...

Barkha: You were measuring ten terrorists by ten guns?

JK Dutt: Yes because I was told that we have to account for ten AK-47s so the number of terrorists we are able to determine by that number. At the same time when the guests were being rescued, we had passed it on to the local authorities that since the information is that some of them may be staying as guests, you have to screen the hostages very carefully.

Barkha: Would you say today that they were ten or could they have been more?

JK Dutt: You see this cannot be ruled out at present but this is a thing that has to be done by the investigating agencies. As far as the shooting was concerned, we were able to account for these ten and these are the ten who were responsible.

Barkha: That others could have come into the country you don't know about that but there were ten inside the hotels that you got at that time.

Dutt: It was not my business to find out.
