The party also claimed that Pakistan for the first time had assured India of action against terrorists who used its territory for planning the attack and accused Congress of criticising its Joint Investigation Team's visit to India due to "political malice".
"We have adequate evidence that Pakistani territory was used and terrorists based there were involved in the attack. They (Pakistan) said they want to send an investigation team. It only strengthens our case and does not weaken it," party national secretary Shrikant Sharma told a press conference.
"Pakistan for the first time has admitted that its territory was used for the attack. It also assured India of action against them. This happened for the first time," he claimed.
He said a probe team from Pakistan had visited Mumbai after the 26/11 terror attacks but nobody had opposed it then.
Just for the sake of criticism, he said, some critics were terming the JIT visit as a clean chit given to Pakistan by the government which, he insisted, was not true.
