India has urged Pakistan to take strong action against the planners of the Mumbai terror attack that killed more than 160 people three years ago.

External Affairs Minister S. M. Krishna said on Saturday that India is waiting for Pakistan to act decisively after New Delhi sent evidence to Islamabad on the alleged planners, who are living in Pakistan.

Saturday was the third anniversary of the attack that saw 10 gunmen lay siege to Mumbai, India’s financial hub, killing 166 people.

Nine of the 10 gunmen were killed in the attack, which was blamed on Lashkar-e-Taiba, a Pakistan-based militant organization.

The gunman who survived is in jail in Mumbai.

India has maintained that Pakistani intelligence helped plan the attack and that Pakistan has not done enough to crack down on those behind it.
