"The extensive, quite precise destruction of this hospital ... doesn't indicate a mistake. The hospital was repeatedly hit," Stokes said. The bombing went on for more than an hour, despite calls to Afghan, U.S. and NATO to call if off, MSF has said. Stokes, who has called for an independent inquiry into the incident, told The Associated Press in an interview in the remains of the hospital on Friday that MSF wanted a "clear explanation because all indications point to a grave breach of international humanitarian law, and therefore a war crime."
