Islamabad on Thursday said New Delhi should provide proof of any Pakistani found involved in terrorist activity on Indian soil.
The statement came after India said Usman, a militant captured on Wednesday shortly he and a fellow militant shot dead two Border Security Force troopers, was a Pakistani.
"We have repeatedly asked India to refrain from accusations," Dawn quoted Pakistan Foreign Office spokesman Qazi Khalilullah as saying.
The accusation was earlier denied Pakistan's National Database and Registration Authority (NADRA).
Dunya news cited official sources as saying that suspect was not a Pakistani as information about him was not found in NADRA's records.
NADRA said images of the terrorist shown on Indian television did not match any Pakistani citizen.
India alleged that the young terrorist Usman, was a Pakistani from the town of Faisalabad who sneaked into India recently.
