With the Pakistani security forces waging a war against militant groups in the NWFP, ISIS said that security of country's "nuclear assets remains in question". "An expansion in nuclear weapons production capabilities, needlessly complicates efforts to improve the security of Pakistani nukes," the report said. Dera Ghazi Khan nuclear site in the recent past had been a target of at least one ground attack by more than a dozen gunmen, the report said adding that a nearby railway line had also been bombed.

CIA chief Leon Panetta said yesterday that US intelligence doesn't have complete track of Pakistani nuclear weapons, but was sure that they were "pretty secure". The US report has urged the American government to prevail upon Pakistan to halt production of fissile material and join talks that would ban production of plutonium and highly enriched uranium.
