Sounds of explosions and drone sightings engulfed the skies of the India-Pakistan border, prompting New Delhi to issue a late-night warning to Islamabad to respect the agreed truce.

Meanwhile, in a defiant address to the nation, Pakistan PM Sharif declared the ceasefire a moment of national triumph, lauding the armed forces for their “professional and effective response” to what he termed Indian aggression.

The ceasefire had been expected to bring a swift end to weeks of escalating clashes triggered by the mass shooting of tourists last month that India blames on Pakistan.
