Morocco's King Mohammed VI waves to the crowd from his car during a rally marking the 40th anniversary of the 'Green March' on November 6, 2015, in Moroccan-annexed Western Sahara's main city of Laayoune. On this date in 1975, the late Moroccan king Hassan II encouraged some 350,000 Moroccans armed with the Koran and the national flag to march to the border with Western Sahara in a show of support for Morocco's annexation of the former Spanish colony.
