In Islamabad, the Pakistan Army alleged that the Indian Air Force violated the Line of Control (LoC) in Muzafarabad sector.
"Indian aircraft intruded from Muzafarabad sector. Facing timely and effective response from Pakistan Air Force released payload in haste while escaping which fell near Balakot. No casualties or damage," Major General Asif Ghafoor, Director General of Inter-Services Public Relations (ISPR), the media wing of the Pakistan Army, said in a tweet.
"Indian Air Force violated Line of Control Pakistan. Pakistan Air Force immediately scrambled. Indian aircraft gone back," he tweeted.
