At least 26 people were killed and 17 others wounded when gunmen opened fire on tourists in Indian-controlled Kashmir, the worst assault in years targeting civilians in a restive region that has seen an anti-India rebellion for more than three decades.

After the deadly Uri attack in September 2016, where 19 Indian soldiers were killed, India launched what it called "surgical strikes" across the de facto border - also known as the Line of Control (LoC) - targeting what it said were militant launch pads in Pakistan-administered Kashmir.

The nuclear-armed rivals, which both claim Kashmir and administer separate parts of it, are at a dangerous crossroad after Tuesday’s militant attack, analysts said.
