MSF on Afghan attack: 'Grave breach in international law'

Aid agency Medecins Sans Frontieres is seeking to invoke a never-used body to investigate the US bombing of its hospital in the Afghan city of Kunduz.

MSF chief Joanne Liu said they did not trust internal military inquiries into the bombing that killed at least 22 people.

The International Humanitarian Fact-Finding Commission (IHFFC) was set up in 1991 under the Geneva Conventions.
