Some of those injured in the bombing of a Medecins Sans Frontieres (MSF) hospital in Kunduz, Afghanistan, have spoken to the BBC about their ordeal.

At least 22 people, including MSF staff, were killed in attacks, which the charity blames on US-led Nato forces.

One man said he saw both doctors and patients burning to death.

President Barack Obama has expressed his deep condolences to the families of victims and the US military has launched an investigation.
