Afghan, Pakistani forces trade air, artillery strikes

KABUL/ISLAMABAD — Afghan and Pakistani forces traded air and artillery strikes into Sunday, with Kabul saying it fired on Pakistani jets over the capital and thwarted an attempted strike on Bagram, as fighting entered a fourth day along their 2,600-kilometer border.

Explosions echoed across parts of Kabul before dawn, followed by bursts of gunfire. Afghan authorities said Pakistani airpower attacked the capital at around 5:40 am local time, triggering a series of blasts and a response from Afghan air defense forces that lasted about 20 minutes.
