Islamabad: Pakistan on Tuesday expressed its "grave concern" over what it called "unnecessary delay" in the investigation of the 2007 Samjhauta Express bombing case.
"Pakistan has conveyed its grave concern to India over (the) unnecessary delay in the free and fair investigation of Samjhauta Express terrorist attack," the Foreign Office said in a statement.
"We also call upon the Indian government to share information about the investigation proceedings of the terrorist attack," it said.
More than 42 Pakistani nationals lost their lives in the bombings, the statement said.
It said that the "Indian attempts to exonerate some of the individuals" involved in the attacks have raised serious questions over the due process of law and dispensation of justice.
Powerful bombs ripped through two compartments of the Samjhauta train, the rail link between India and Pakistan, during the intervening night of February 18 and 19, killing 68 people.
NIA has filed charge sheet against eight people including Naba Kumar Sarkar alias Swami Asimanand, Sunil Joshi (deceased), Ram Chandra Kalsangra, Sandeep Dange and Amit (absconding), Lokesh Sharma, Kamal Chauhan and Rajender Choudhary in the case which is under trial.
