The 32 airports are now available for civil aircraft operations with immediate effect, the Airports Authority of India said in a statement.

Pakistan’s airport authority fully reopened its airspace on Saturday.

India’s top airline, IndiGo, said it will progressively commence operations on previously closed routes.

However, on Sunday, Pakistan aviation sources reported that at least 150 flights have been canceled, including 45 from Karachi Airport, 38 from Lahore, 40 from Islamabad, 10 from Multan, and 11 from Peshawar.

Also, on the same day, violations were reported from the main cities of Indian Kashmir, the territory that had borne the brunt of four days of fighting.

Pakistan and India on Saturday agreed to an immediate ceasefire, hours after Pakistan launched an operation to exercise its right of self-defence following the Indian missile attacks.
