KABUL: Gunmen disguised as policemen stormed a television station in Kabul on Tuesday, killing at least two people and wounding several others in the latest deadly attack on Afghan journalists. The assault, claimed by the Islamic State group, lasted about three hours before Afghan special forces overpowered the attackers armed with guns and grenades and freed staff trapped inside the building. “This is an attack on freedom of media but they cannot silence us,” Shamshad news director Abid Ehsas told rival Tolo News at a hospital in the Afghan capital where some of his wounded colleagues are being treated. The station reported that one attacker blew himself up at the gate. Another attacker went inside and shot at staff before going up to the roof to fire on security forces. Islamic State claimed responsibility for the attack in a statement released by their Amaq propaganda agency. The Taliban had earlier released a Twitter statement denying involvement.
