Demonstrators throw molotov cocktails over the gates of Mexico's National Intelligence Centre on the eve of 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. The Mexican government has recently promised to provide the parents of the young people with all available information on the case, which a commission of international experts has found to implicate the army.
