India's civil aviation authorities have closed the country's airspace to Pakistani registered aircraft in further deterioration of relations between neighboring states.
The measure appears to be a ban on retaliation after Pakistan implemented similar restrictions on Indian aircraft on April 25th.
Tensions between India and Pakistan rose after attacks on Pahargam tourists in the Indian-controlled Jammu and Kashmir regions.
On April 30, effective Notam, Indian authorities list the ban being applied to four flight information regions: Delhi, Mumbai, Chennai and Kolkata, which cover the entire country.
India's airspace is “unavailable” for aircraft registered by Pakistan or aircraft owned or leased by Pakistani operators, Notam said. This includes military flights.
Like Pakistani counter vans, India's restrictions cover all altitudes.
Pakistan's airspace bounds most of the country's land borders, but India spreads over a wide range of waters, with fir from Mumbai, Chennai and Kolkata covering the Arabian Sea and most of the Bay of Bengal.
