Nur Khan air base is home to Pakistan's main transport squadrons and is used for logistical and strategic airlift operations.

Pakistan said India fired missiles at three air bases inside the country Saturday but most of the missiles were intercepted and that retaliatory strikes on India were underway. It’s the latest escalation in a conflict triggered by a massacre last month that India blames on Pakistan.

Powerful explosions were reported early Saturday across multiple Pakistani air bases, including a critical installation near the capital Islamabad, prompting the Pakistani government to shut down the country's airspace to all civilian and commercial traffic.
