The U.S. State Department issued a fresh travel warning for Pakistan after an Indian drone attack hit a target in Lahore, warning U.S. citizens to leave areas of active conflict if it is safe or to shelter-in-place.

India said it had targeted Pakistani air defense and radar systems in retaliation against attempted strikes on its military facilities. Pakistan said it had downed Indian drones in various locations, but one had hit a military site near Lahore, wounding four soldiers.

“Due to reports of drone explosions, downed drones, and possible airspace incursions in and near Lahore, the U.S. Consulate General in Lahore has directed all consulate personnel to shelter-in-place,” the State Department said in a post on X, formerly Twitter.

“The Consulate has also received initial reports that authorities may be evacuating some areas adjacent to Lahore’s main airport.
