An attack on tourists in India's Himalayan territory of Kashmir this week sparked a new crisis between nuclear armed South Asian neighbours India and Pakistan, with New Delhi blaming militants with "cross-border linkages" for the killings.

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.

Scores of tourists returned safely to Mumbai on April 24 after a terror attack in Kashmir claimed over two dozen lives, most of them from Maharashtra. The returning tourists were greeted with white roses and chocolates by local politicians at the Mumbai international airport.
