After dragging its feet over the Mumbai terror strike case, Pakistan today demanding that the perpetrators of the bombing of the Samjhauta Express train should be brought to justice. The demand comes in the back drop of RSS leader Aseemanand's confession about the involvement of Sangh activists in several terrorist attacks, including the 2007 bombing of the Samjhauta Express that killed nearly 70 people, a majority of them Pakistanis.Foreign Office spokesman Abdul Basit said this in Islamabad while responding to a question on Pakistan's reaction to Aseemanand's confession.
