A day ahead of midterm elections in Mexico anti-Government protesters have violently clashed with police.<br /><br />The government has moved some 40,000 members of security forces in to restive southern states in a bid to safeguard the vote.<br /><br />In Oaxaca at least two officers were captured by protesters who want a boycott of the elections.<br /><br />They are angry about the continued internal strife and gang violence that has claimed more than 100,000 lives in the last eight years.<br /><br />Perhaps the most high profile case involves the disappearance, last September, of 43 student teachers in Guerrero state. <br /><br />The demonstrators say they were almost certainly massacred by drug cartels in league with local police.<br /><br />The lower house of Mexico’s Congress, nine state governorships and more than 1,000 posts in state legislatures and mayors’ offices are up for grabs in Sunday’s election. <br /><br />Sunday’s vote is the first test for President Enrique Pena Nieto since he was elected in 2012 on a mandate to bring peace to Mexico
