India said Tuesday it was not planning military action against Pakistan in response to the deadly Mumbai attacks but warned that its relationship with its rival would not be "normal" until Islamabad takes action against terrorists. Indian authorities have blamed the Pakistani militant group Lashkar-e-Taiba for the three-day siege that left 164 dead in Mumbai last month. Pakistan has arrested a senior Lashkar leader who was the suspected mastermind of the attacks and shuttered the offices of a charity linked to Lashkar. Authorities there say they will prosecute anyone allegedly involved in the attacks in their own courts. But Indian leaders have said the moves are not sufficient and have called on Pakistan to do more to dismantle the terror network they claim is well-established in that country. Defense Minister A.K. Antony said India was "not planning any military action" against Pakistan but urged Islamabad to crack down on militants thought to be based within its borders.
