He criticised the media for reporting that a US delegation had met prime minister to discuss the California shooting adding that the report was false and no such meeting took place.
Nisar, however, claimed that Pakistan has assured US authorities of full cooperation during their probe into the matter.
California shooting
Two heavily armed attackers opened fire on a banquet at a social services centre for the disabled in San Bernardino, California, on Wednesday, killing 14 people and seriously wounding more than a dozen others.
The duo were later indentified as Syed Rizwan Farook, 28, and Tashfeen Malik, 27.
According to local news reports Farook was employed by the San Bernardino County health department which is believed to have organised the party at the Inland Regional Center while the female shooter, Tashfeen Malik was of Pakistani origin and had pledged allegiance to Islamic State leader Abu Bakr al-Baghdadi,
The couple were shot dead later in the day in a shoot out with law-enforcement officials.
The attack was the deadliest mass shooting in the US since the 2012 assault on an elementary school in Connecticut that left 26 people dead, including 20 children.

IS also claimed responsibility for a Nov 13 series of attacks in Paris in which gunmen and suicide bombers killed 130 people.
