Three American doctors have been killed in Afghanistan.
FOX News Radio's Emily Wither reports:
The three doctors were working at an international hospital in the capital Kabul when an Afghan security guard working there turned his gun on them. Two others were injured.
A spokesman for the Interior Ministry says he's now in custody:
(Spokesman) "Police have arrested the attacker as well, so we will investigate to find out the motives behind this attack."
Attacks on foreigners working in the country are becoming more common. Just a few weeks ago two journalists were shot by a police commander while covering the elections.
