New Delhi: India’s upcoming tri-services exercise, Trishul, along the border seems to have rattled Pakistan.
In a notification to airmen (Notam), Pakistani authorities have restricted multiple air traffic routes across its central and southern airspace without specifying any reason.
The Notam, issued for October 28-29, could be linked to a military exercise or a possible weapons test, reported India Today.

Islamabad’s move follows India’s announcement of a large-scale tri-services military exercise, to be conducted near Sir Creek along the Pakistan border, from October 30 to November 10.
The airspace reserved for Trishul exercise extends up to 28,000 feet, as per satellite images shared by geo-intelligence and OSINT (open-source intelligence) expert Damien Symon.
According to Symon, the selected area and scale of operations for Trishul were ‘unusual’. It will be one of the biggest joint operational drills in recent years.

According to the Defence Ministry, the exercise involving the Indian Army, Navy and Air Force, is designed to demonstrate the joint operational capabilities, atmanirbharta (self-reliance) and innovation of the forces.
“Troops from Southern Command will actively participate to validate joint operations across diverse and challenging terrains, including offensive manoeuvres in the creek and desert sectors, amphibious operations off the Saurashtra coast, and joint multi-domain operational exercises,” Defence Ministry said in a statement.
Both countries have been issuing Notams for military exercises along the borders since Operation Sindoor in May.
Pakistan’s latest response suggests it is keeping a close watch on India’s activities near the border.
Earlier this month, Defence Minister Rajnath Singh had cautioned Pakistan against any misadventure in the Sir Creek area, around Sindh and Karachi.
An uninhabited, mostly inaccessible marshland between Gujarat and Sindh in Pakistan, Sir Creek is a 96 km estuary, strategically significant for security and military planning.
