Pakistan has backed the Indians' claims that it is house fighters of the armed group who claimed responsibility for last week's deadly attacks on a paramilitary convoy in Indian-administered Kashmir.
Thursday's car bomb attack, which killed 42 people from the Central Reserve Police Force (CRPF), was alleged by the Pakistani-based Jaish-e-Mohammad (JeM).
After the blast, New Delhi called for "Pakistan's complete isolation" with Prime Minister Narendra Modi promising a "strong response".
"If our neighbor thinks it can destabilize India, then make it a big mistake," Modi said Friday.
On Sunday, Islamabad rejected New Delhi's accusations and said they were "knee-jerking" and made without thorough investigation.

"Bloody, war, and the exercise of appropriate standards to suit internal political interests are both misleading and counterproductive.
" India must come out of the denial menu, end state oppression against the kashmiri youth, address widespread alienation in the IOC and pursue The dialogue, "added the statement.
The bombing ratcheted the tension between the two South Asian neighbors who control parts of the Muslim majority Kashmir while claiming the entire territory as their own. India has for years accused Pakistan of supporting separatist groups in split Kashmir.
] Pakistan insists that it only gives political support to Kashmir's oppressed population.
