The offensive occurred amid heightened tensions between the nuclear-armed neighbors in the aftermath of an attack on Hindu tourists in Indian Kashmir.

Indian forces have attacked Pakistan with missiles in three locations, Pakistan’s military spokesman is quoted by the country’s state TV as saying. There are also reports of intense shelling and loud explosions in border areas of the Pakistan-administered state of Kashmir, according to Reuters news agency.

The Indian military said early Tuesday it had launched strikes against Pakistan in retaliation for last month’s militant attack in Indian-administered Kashmir.
