A suicide bomber has killed seven employees of a popular Afghan news TV channel in the capital Kabul and injured a further 25 people.

The attacker drove a car containing explosives into a minibus carrying the TOLO employees, which the Taliban recently labelled “satanic”, on Thursday morning (AEDT).

“Unfortunately, in the terrorist attack today in Darulaman Road in Kabul, we lost 7 staff members,” TOLO posted on Facebook.

“We condemn these terrorist attacks that kill innocent Afghans.

“We await for an update from security and government officials on the details of the attack. Our deepest condolences to the families.”

The targeted journalists were reportedly from the TV channel’s graphics and dubbing departments.

The Taliban declared TOLO and another channel, 1TV, as “military targets” late last year because they both reported accusations of rape and murder by Taliban fighters during their brief capture of Kunduz in September 2015.

“The enemy of humanity, peace and Islam martyred our colleagues because they were exposing their crimes,” TOLO news presenter Fawad Aman told the channel’s viewers after the attack, according to Yahoo News.

“They martyred you to silence us, but they will never achieve this evil goal.”

TOLO is reportedly one of the most active media outlets in Afghanistan, where the advocacy group Reporters Without Borders ranked press freedom 122 out of 180 nations.

No group has claimed responsibility for the car bombing.
