India said on Monday it had responded to 'unprovoked' small arms firing from Pakistan along the de facto border for the fourth consecutive night, as it deepens its search for militants in the region following last week's deadly attack on tourists in Kashmir.

Tensions between India and Pakistan are running high in the aftermath of the Pahalgam terror attack. Amid fears of a military escalation, Pakistan Air Force has received express deliveries of China’s advanced PL-15 long-range air-to-air missiles.

China has urged India and Pakistan to exercise restraint and avoid further escalation following the deadly terror attack in Pahalgam, Jammu and Kashmir, which killed 26 people, mostly tourists. As a neighbour of both countries, Beijing said it welcomed any measures that would help cool tensions.
