NEW DELHI/ISLAMABAD — Tensions are escalating between India and Pakistan following a deadly attack on tourists in Pahalgam in the Kashmir region last week, heightening fears of a wider conflict between the nuclear-armed neighbors.

India blames Pakistan for the April 22 attack that killed 25 Indians and one Nepalese. Islamabad has denied any involvement. A little-known group called Kashmir Resistance, which some media reports suggest is linked to Pakistan-based militant outfit Lashkar-e-Tayyaba, initially claimed responsibility and then denied its role.
