KHARTOUM:Sudanese air force bombs have hit a Doctors Without Borders hospital in South Kordofan, the group said Tuesday, adding to Western concerns about attacks against civilians in a largely-hidden war.

Paris-based Medecins Sans Frontieres said its facility in Farandalla, South Kordofan, was “attacked.”

Sudan’s military denied the incident, the second case of its kind involving a hospital in the past few weeks.

“As bombs struck the village of Farandalla on June 16, two hit the MSF hospital there. Five people were wounded in the village and one MSF staff member was injured at the hospital,” the international aid group said in a statement.

“We are shocked that a medical facility can be bombed, especially since it was clearly identified with a flag and a cross on the roof,” said MSF head of mission Brian Moller. “We also had previously communicated the hospital’s position to the authorities in Khartoum.”

Sudan’s military spokesman Sawarmi Khaled Saad told AFP no air force planes had been used in the area.

“We did not attack any hospital there because our target is not civilians,” he said.

Bombs destroyed the emergency room, a dressing room, the pharmacy, and the hospital kitchen, MSF said, describing damage as “significant.”

“But MSF will continue to work there,” Moller said.

The US ambassador to the United Nations last week accused Khartoum of intensifying attacks on civilians in South Kordofan and Blue Nile states.

Ground and air strikes have increased since April, with hundreds of barrel bombs and other ordnance dropped on towns and villages, deliberately targeting hospitals and schools, Ambassador Samantha Power said.
