Pakistan has said its forces killed 71 terrorists "backed and sponsored" by Afghanistan and India in security operations across southwestern Balochistan province over the past 96 hours.
Weapons, ammunition and explosives were also recovered during the operations, the Pakistan Army said in a statement on Saturday.
Kabul and New Delhi have so far not responded to Islamabad's accusation.
Afghanistan, for its part, said its forces killed 28 terrorists and wounded 32 in the eastern province of Nuristan after alleged Daesh operatives crossed from Pakistan.
Pakistan, however, rejected the claim as "frivolous, baseless and devoid of any truth".
"Pakistan categorically rejects the fabricated claims of involvement by its security forces or intelligence agencies in any internal clashes in Nuristan or elsewhere in Afghanistan, including allegations of recruiting or training former Afghan security personnel or facilitating Daesh or any other terrorist group operating in Afghanistan," the information ministry said in a statement.
Pakistan, which has seen a series of terrorist attacks on its soil in recent years, accuses India and Afghanistan of patronising terrorist groups.
India and Afghanistan reject the accusations.
Islamabad has repeatedly urged the interim Taliban administration to rein in the terrorists of Tehrik-i-Taliban Pakistan (TTP), a conglomerate of several terror groups.
Pakistan alleges that the Taliban government in Afghanistan has allowed TTP terrorists to operate from Afghan soil, while Kabul denies the charges and reaffirms that it does not permit attacks against Pakistan from its territory.
Terror attacks have surged in northwestern Khyber Pakhtunkhwa since the US-led withdrawal and the Taliban’s return, largely led by the TTP.
Earlier this month, at least 31 people, including 16 police personnel, were killed in an explosion and gun attack at a police headquarters in Kohat, in KPK province.
On Thursday, Pakistan carried out air and drone strikes against 10 locations in Afghanistan after detecting and neutralising drones launched from Afghan territory.
Islamabad described the strikes as "deliberate, precise, calibrated and proportionate", saying they were strictly limited to identified military targets that Pakistan said were directly linked to the attempted attacks.
Pakistan called on the Afghan Taliban to immediately cease hostile activity against Pakistan and take "effective, concrete, verifiable and sustained action against terrorist entities" operating from Afghan territory.
