The attack on Shamshad TV began with an explosion as an attacker blew himself up at the gate of the station. Gunmen then stormed the building.
“People dressed in police clothes came in and initially threw hand grenades, which killed one of our guards and wounded another,” Abed Ehsas, Shamshad’s news director, told broadcaster Tolo News TV.
“After that, others got into our building and started firing. Some of our colleagues were hit, though, thank God, many others managed to get out. Some were wounded by gunshots, falling glass and when they jumped from high floors,” he added.
The wounded guard died shortly later.
The attack lasted about three hours. Afghan special forces freed the staffers who had been trapped inside the building and killed at least one assailant.
It was not clear how many terrorists had been involved. An eyewitness told AFP he had seen three.
The Pashto-language broadcaster had gone off the air and was transmitting only a still image during the attack. But it resumed broadcasting later, saying the assault had ended.
