Pakistan has rejected an Afghan claim that it was involved in a massive bomb attack in the capital, Kabul.
Wednesday's attack close to the heavily protected diplomatic area killed about 80 people and injured about 350 others.
Afghan intelligence NDS officials suggested the Haqqani network - militants allied with the Taliban - carried it out with Pakistan's support.
Pakistan's foreign ministry spokesman described the claim as baseless.
Stability in Afghanistan was in Pakistan's interests, said Nafees Zakaria, and the "rhetoric of blaming others" to hide Afghanistan's own failures was unhelpful.
Pakistan and Afghanistan frequently accuse each other of supporting and harbouring militants who carry out cross-border attacks. Afghanistan on Wednesday cancelled all planned cricket fixtures with Pakistan in response to the blast.
The Taliban has denied any role in the attack and the ISIS has claimed responsibility for the Kabul attack but the Afghan Intelligence Agency NDS insists that Pakistan was behind the attack.
