Later, PML-N Vice-President Maryam Nawaz also expressed sorrow over the incident in a tweet.

"I and the [entire] nation salute the brave sons of the country," she said, referring to the martyred pilots.

Two similar incidents of aircraft crashes were reported in August this year. However, no loss of life was reported following either of the incidents.

The first incident had taken place near Attock in Punjab when a Pakistan Air Force (PAF) fighter trainer aircraft had crashed during a routine training mission on August 6.

According to a statement issued by a PAF spokesperson at the time, both the pilots had ejected from the jet successfully and no loss of life or property was reported on the ground.

Few days later on August 12, a Mushshak aircraft had crash-landed in the fields of Chammala village near Jhelum due to a technical failure and both the pilots inside the aircraft had received minor injuries.
