Four days after India conducted “surgical” military strikes inside Pakistan-held Kashmir, South Asia’s rival nuclear-armed states continue to teeter on the brink of war.There have been hours-long artillery and gun-fire exchanges across the Line of Control (LoC) that separates Indian- and Pakistani-held Kashmir each night since India sent troops and helicopters into Pakistan and inflicted “double-digit” casualties.Late Sunday evening, India claimed that an army camp in Barmulla in the Kashmir Valley had come under terrorist attack and that at least one Indian solider had been killed and one injured.India has repeatedly held Pakistan responsible for terrorist acts on its soil, most recently for the September 18 attack that anti-Indian Islamist militants mounted on the Uri military base in Jammu and Kashmir.
