NEW DELHI — A total of 21 airports across northern and northwestern India will remain closed until Saturday, according to a senior police official.

“All airports have been sealed. No one will be allowed to go in or out except for security personnel and staff,” Shri Sirivennela of Amritsar Police told Indian news agency ANI, adding that “all scheduled flights” in the region will be impacted.

“Until the situation is under control, we will be following the decisions made by the central government,” Sirivennela told ANI.

Multiple Indian and international carriers issued travel advisories on Wednesday regarding cancellations to and from destinations in northern India, after New Delhi launched strikes on Pakistan and Pakistani-administered Kashmir on Wednesday morning.

Other airlines said they were re-routing or canceling flights to and from Europe due to the escalation between India and Pakistan, with more than two dozen international flights diverted to avoid Pakistan airspace, according to FlightRadar24 data.

Late on Wednesday night (Thursday morning local time), Reuters reported that Pakistan had reopened its airspace and that its airports were fully functional.

Pakistan has reopened its airspace after closing it following India’s missile strikes in Pakistan and Pakistan-administered Kashmir, Reuters reported.

The country’s airports are now “fully functional,” according to Reuters, citing Pakistan authorities.

On Thursday morning, flight tracker website FlightRadar24 showed some passenger planes flying over Pakistan again – though most flights are still steering clear of the Pakistan-India border.

Pakistan closed airspace around Lahore and the coastal city of Karachi on Wednesday morning after India launched a series of early morning strikes on locations in the country’s north. There were major flight disruptions, with India also closing some of its airports near the border region and multiple international airlines avoiding flying over Pakistan. — CNN
