What counts as a war crime?

Almost two weeks of fighting between Israeli forces and Palestinian militants has left more than 200 people dead — almost all of them in Gaza. The International Criminal Court warns both sides may have committed war crimes — in this week’s Sitrep, we learn more about the laws of war, and ask whether anyone will be held to account if they’re being broken. We hear from the RAF’s commander for Middle East operations, who warns the Islamic State group it has “nowhere to hide”. A former National Security Adviser tells us Britain needs to decide what role it wants to take in the world post-Brexit. And we ask why the Army commissioned a report to establish its economic value to the UK, and find out what it says.
