Growing social unrest in Mexico culminated in a mass protest on the streets of its capital Thursday, with reports of fierce clashes between demonstrators and police.
The incident marks yet another example of months of popular anger against the government, with analysts signaling that the unrest has weighed on consumption and investment at a time of falling oil prices.
Tina Fordham, a political analyst at Citi said Thursday's clashes were an important development and said tensions were an example of "vox populi risk" - changing public opinion that is becoming increasingly volatile.
The troubles followed on from three separate marches in Mexico City during the day, with protesters then descending on the central square of Zocalo in the heart of the city, according to Reuters.
Police used tear gas to disburse the crowds after rocks and Molotov cocktails were thrown at the presidential palace, according to the reports. This followed on from similar clashes seen close to the city's airport.
The government is facing a growing backlash over the fate of 43 missing students who have not been seen since late September. There have been accusations that corrupt officials handed over the students over to members of a drug gang with the country's attorney general saying that that the students were allegedly killed with their bodies then burned.
Carlos Capistran, a Mexico economist at Bank of America Merrill Lynch, believed that Mexico has entered a new period of social unrest, even before the news of Thursday's protest became apparent.
"This is weighing on consumption and investment, contributing to a weaker-than-expected recovery. We expect unrest could continue ahead of the elections in 2015," he said in a research on Thursday morning.
