Outraged residents set one of the doors of Mexico’s ceremonial presidential palace on fire in Mexico City this weekend after the country’s attorney general said the 43 student protesters missing since September were likely massacred and that their remains may have been burned by criminals working in association with police.

Mexican President Enrique Pena Nieto does not live in the palace but rather in another official building elsewhere in the city. From the Guardian:

The group, carrying torches, broke away from what had been a mostly peaceful protest demanding justice for the students, who were abducted six weeks ago and apparently murdered and incinerated by corrupt police in league with drug gang members.

Police put out the flames and enforced fencing designed to keep the protesters away from the National Palace, which was built for Hernan Cortes after the Spanish conquest and now houses Mexico’s finance ministry.
