SINGAPORE (Reuters) - India will feel pressured to retaliate if Pakistan-based militants launched an attack similar to the Mumbai assaults, a government minister said on Saturday. The Indian governments response was restrained despite the public calls to hit back over the November 2008 attacks blamed on a Pakistan-based guerrilla group, but it would be difficult to withstand the pressure again, Minister of State for Defence M M Pallam Raju told a security conference. If a provocation is to happen again, it would be hard to justify to our people self restraint, and I hope that it will not be repeated and that we will have a constructive dialogue with Pakistan in containing these terrorist elements which are causing strife not only in India but also within Pakistan, Raju said. India blames members of Lashkar-e-Taiba (LeT) for the attacks. Pakistan has put seven people on trial, and says it needs more evidence from India to prosecute others including the founder of the LeT, Hafiz Mohammad Saeed. Raju said revelations made by a Pakistani-American who has confessed to scouting targets for the Mumbai attacks in a trial in Chicago in which he linked the attacks to the ISI have made it harder to show restraint in future. The international community is aware of the damning evidence that has come out from David Headley during his interrogation, Raju told the conference in Singapore.
