Seeing their colleagues and patients die was a horrifying shock, according to survivors of the deadly air raid on a hospital in Afghanistan. The tragedy, medical staff said, simply cannot be dismissed as “collateral damage” from a botched airstrike.

Recalling the tense minutes of continuous airstrikes which hit the Medecins Sans Frontieres (MSF) hospital in Kunduz, NGO staff said that the destruction of the hospital is nothing short of a “grave violation of international humanitarian law.”
