Police in Indian-controlled Kashmir say an explosion aboard a tourist bus has killed six people in the main city, Srinagar.
More than a dozen other people were injured, most of them Indian tourists. The bus was traveling to the popular tourist destination of Shalimar Garden on Sunday.
Police say they are unsure what caused the explosion.
Last year, at least 12 Indian tourists were killed and dozens more injured during a series of bombings by suspected militants fighting India's rule in the region.
