ISLAMABAD - Pakistan has recalled its ambassador in New Delhi for consultations amid escalating tension with nuclear-armed neighbour India, Pakistan's foreign office spokesman said on Monday.

"We have called back our High Commissioner in India for consultations. He left New Delhi this morning," Foreign Office spokesman Mohammad Faisal said on Twitter.

India recalled its ambassador to Pakistan last week to discuss Pakistan relations in the wake of a suicide bombing in the disputed Kashmir region that killed 44 Indian paramilitary police.

New Delhi says Pakistan had a hand in the attack, which Islamabad denies.

The Pakistan-based Jaish-e-Mohammed (JeM) armed group claimed responsibility for the worst attack on Indian soldiers in decades, drawing a sharp reaction from New Delhi.

Indian Prime Minister Narendra Modi promised a strong response to the suicide attack on a military convoy in Kashmir's Pulwama district on Thursday.(FA)
