Two local employees of the Afghan Red Crescent Society (ARCS) have been killed in a ‘shocking’ attack in the north of the country, Red Cross and Red Crescent officials said Wednesday.

Two other staffers were injured in the shooting Tuesday on a main road in the Khanaqa district while their mobile clinic was travelling to the provincial capital Shiberghan, officials said. They described the killings as ‘shocking and unacceptable’ but said the identity of the attackers was unknown. "It looks like they were deliberately attacked. The vehicle was clearly marked," said Robin Waudo, communication director of the ICRC.

The four-member mobile clinic team was providing medical help to people living in remote areas, the ARCS, ICRC and the International Federation of the Red Cross and Red Crescent Societies said.
