People take to the streets in Mexico City on the ninth anniversary of the high-profile, unresolved disappearance of 43 students in 2014.
The students, from the Ayotzinapa Rural Normal school, disappeared between the night of September 26 and the early morning of September 27, 2014, when they were traveling via bus to participate in demonstrations in Mexico City. Investigators say the students were detained by corrupt police and handed over to a drug cartel but many of the details remain unclear.
