Seven were killed and at least 25 injured by a suicide car-bomb attack that targeted a bus carrying journalists working for an Afghan news channel, officials told Reuters.

The Taliban claimed responsibility for the attack. "If they do not stop their evil activities this will not be the last attack on them," a Taliban spokesman said in an emailed statement to Reuters.

Kabul Police Chief Abdul Rahman Rahimi said a Tolo News vehicle was specifically targeted, Reuters reported.

Tolo News is a 24-hour news channel in Afghanistan. In October, the Taliban designated Tolo News and 1 TV, another Afghan news outlet, "military objectives" and accused them of spreading propaganda.

The Afghan outlets had reported allegations that Taliban fighters had committed rapes in the battle for Kunduz, among other abuses. Abuse was also reported by Western media, citing the Afghan government and a report by an Afghan-rights group.

Tolo TV confirmed in a series of tweets that seven of its staff members had been killed. Tolo News reported that the bus targeted was carrying employees of Kaboora Production, a production company affiliated with Tolo TV, Tolo News, and other Afghan media outlets.

While initial reports noted the proximity of the attack to the Russian embassy, Radio Free Europe reporter Frud Bezhan reported that Russia's foreign ministry said the attack was "not aimed against our diplomatic mission" and that Russians were not among the injured.

Afghan President Ashraf Ghani immediately condemned the attack in a statement, according to Tolo News. Afghanistan's chief executive officer, Abdullah Abdullah, also released a statement condemning the attacks in which he said the journalists who were attacked had been working with "integrity and impartiality in difficult conditions to inform the public of the true nature of the Taliban and the terrorists," according to a translation.

Images from the scene have begun to appear on social media and wire services.
