Two armed gunmen and one civilian were dead after a two-hour long attack on a hospital in southern Afghanistan ended Monday, an official said.
The civilian was a member of the staff at Kandahar's Mirwais hospital. Two others, including another hospital employee and one security force member were wounded, said Zia Ul Rahman Durani, Kandahar police spokesman.
"The gunmen were disguised as doctors," Durani said, adding that a firefight ensued when hospital security identified the attackers in the hospital.
No group has yet claimed responsibility.
Funded by the International Committee of the Red Cross, Mirwais hospital is one of the largest medical facilities in the country's south, providing health services for more than 5 million people. It also has a separate department for treating those injured in war.
The United Nations Assistance Mission in Afghanistan (UNAMA) recently called on all parties to the country's ongoing fighting to "always respect the provision of healthcare, never to harm medical personnel and patients and to ensure that the protected status of medical facilities is respected."
The statement added that intentional attacks on such facilities "constitute violations and abuses of international human rights law."
