US President Barack Obama has apologised to medical charity Médecins sans Frontières (Doctors Without Borders) following the bombing of a hospital in Afghanistan, the White House said.
The air strike at the MSF-run hospital in Kunduz killed 22 people, including three children.
A MSF staff member who managed to escape the bombing raid on the hospital in Kunduz has told of his horror as he saw the building "engulfed in flames".
Heman Nagarathnam, MSF Head of Programmes in northern Afghanistan said: “The bombs hit and then we heard the plane circle round."
The aid agency said the hospital was bombed in a series of raids at approximately 15 minute intervals between 2:08am until 3:15am local time.
There could be a long wait for answers as to how and why Kunduz hospital ended up being on the receiving end of US air strikes.
Medical charity worker relates how he and colleagues tried to save patients and staff following devastating air strike.
