KABUL: Afghanistan said it was firing at Pakistani jets in Kabul after blasts and gunfire rocked the capital on Sunday, compounding instability in a region rattled by US–Israeli strikes on Iran and retaliatory attacks on US targets in Gulf states.

The Taliban-ruled state has suffered Pakistani strikes against government installations over the past week following accusations, which it denies, that it harbors militants.

The heaviest fighting in years between the neighbors has raised fears of a protracted conflict ‌along their 2,600-km (1,615-mile) ‌border, with several countries including Qatar and Saudi ​Arabia ‌calling ⁠for restraint ​and ⁠offering to help mediate a ceasefire.

Explosions echoed across parts of Kabul before sunrise, followed by bursts of gunfire, a Reuters witness said. It was not clear what had been targeted or whether there were casualties.

Taliban administration spokesperson Zabihullah Mujahid said the sounds were the result of Afghan forces targeting Pakistani aircraft over the capital.
