India said its troops responded to firing from Pakistan military positions in the Jammu and Kashmir region for a second day on Saturday, as tensions remained escalated between the neighbors after a deadly attack on tourists this week.

India and Pakistan have intensified their hostilities over the hotly contested Kashmir region following a massacre of 26 mostly Indian tourists, which New Delhi linked to Pakistan. Pakistan denies it was behind Tuesday's attack by gunmen on a group of tourists in Kashmir.

The attack triggered outrage and grief in India, along with calls for action against Pakistan, which New Delhi accuses of funding and encouraging terrorism in Kashmir.
