Pakistan has continued a limited opening of its airspace for commercial flights, after closing it earlier this week at the height of tensions with neighbouring India that saw both countries carry out air raids inside each other's territories for the first time since the 1971 war.
Pakistan's civil aviation authority said on Sunday it was allowing restricted operations at the Allama Iqbal international airport in the eastern city of Lahore.
This comes after partial operations at Karachi, Quetta, Peshawar and the capital, Islamabad, resumed on Friday.
Other airports in Gilgit Baltistan, Punjab province and the interior Sindh region remained closed on Sunday.
The travel restrictions are expected to be lifted on Monday at 1pm local time (08:00 GMT), according to the country's civil aviation authority.
International and domestic air travel in the region has been widely disrupted, with several airports in Pakistan and India shut, flights rerouted and suspended, amid fears of a major military escalation between the South Asian nations.
