GHAZNI, Afghanistan: Two patients and a caretaker were killed during an overnight raid by Afghan forces on a health clinic in the central province of Wardak, the Swedish Committee for Afghanistan, the aid group which runs the facility, said on Thursday.

The aid group said the information it had received indicated the Afghan National Army had conducted the raid on the clinic in the Tangi Saidan area of Wardak late on Wednesday night and it called for those responsible to be held accountable.

“This attack constitutes a gross violation of humanitarian principles and the Geneva Convention that all actors of a conflict have to respect,” Jorgen Holmstrom, Country Director of SCA, said in a statement.

“Medical facilities and medical staff are to provide treatment to anyone in need and patients are to be granted safety according to humanitarian law,” he said.

Provincial government spokesman Hemat, who like many Afghans goes by one name only, said a special forces unit conducted an operation in the Tangi Saidan area of Wardak and killed four insurgents.
