Thanks for the map of the Sinjar Mountains with “Iraqi Yazidis fleeing into war-torn Syria” [news, Aug. 9]. Maps can be very helpful in understanding the complete picture of a news event. Showing the area and its relation to Iraq (and Kurdistan), Syria and other territory taken by the Islamic State and showing the topography helped to demonstrate the jeopardy of the Yazidis and the difficulties in providing relief. I look forward to such geographic enhancements to readers’ understanding of events, especially in less well-known regions of the world.
