The India Ministry of External Affairs has summoned Pakistani High Commissioner Shahid Malik to lodge a formal protest against Pakistan's inaction against terrorist groups operating in India, reported local NDTV yesterday.

This diplomatic gesture came under the background of growing tension between the two nations after the Mumbai attacks.

Previously, Pakistani Prime Minister Yousuf Raza Gilani told Indian Prime Minister Manmohan Singh that Pakistan had nothing to do with the Mumbai attacks.

On Friday, Pakistani President Asif Ali Zardari too rejected charges of Pakistan's involvement in the coordinated terrorist strikes. Pakistan could not "gain anything" for such attacks and its democratic government did not believe "in such tactics", Zardari told German Ambassador Michael Koch during a meeting.
