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.

During a phone call with his Pakistani counterpart Ishaq Dar, Chinese foreign minister said China is closely following developments after the Pahalgam attack.
