In August 1933, incidents like the Simele massacre caused tension between the United Kingdom and Iraq. Prime Minister Ramsay MacDonald ordered High Commissioner Francis Humphrys to Iraq immediately upon hearing of the killing of Assyrian Christians. The British government demanded that Faisal stay in Baghdad to punish the guilty, whether Christian or Muslim. In response, Faisal cabled to the Iraqi Legation in London: "Although everything is normal now in Iraq, and in spite of my broken health, I shall await the arrival of Sir Francis Humphrys in Bagdad, but there is no reason for further anxiety. Inform the British Government of the contents of my telegram."
