The United States has called on both India and Pakistan to resolve their differences peacefully following the deadly April 22 attack in Pahalgam. A State Department spokesperson said the US is monitoring the situation closely and remains in contact with both countries at several levels.

Pakistan denies involvement, India remains skeptical, citing evidence of Pakistan-based terrorist groups' involvement.

Asif said Pakistan was on high alert and that it would only use its arsenal of nuclear weapons if "there is a direct threat to our existence".
