Mexico City, June 3 (teleSUR-RHC)-- A wave of violence targeting public institutions to protest Mexico's June 7th midterm elections has included bombings and destruction of electoral property across the country in recent days.

Members of the Guerrerense social movement, who oppose this Sunday’s elections, burned thousands of voting ballots in front of the municipality of Tlapa after breaking into the city’s electoral headquarters on Tuesday, Mexican newspaper El Universal reported.

“Alive you took them, alive we want them back!” protesters shouted in reference to the disappearance of 43 students of Ayotzinapa who were attacked by police and disappeared on September 26, 2014. The parents of the missing students oppose the elections and have called for their boycott due to lack of state accountability. “There won’t be elections! There won’t be elections!” demonstrators reportedly shouted as they burned the voting ballots containing the pictures and names of the candidates running for state governor, local deputies and mayors.

The same day four people were injured after an explosive detonated at a government office where electoral offices are located in the municipality of Matamoros, in the northern state of Tamaulipa, on the border with the United States. Perpetrators of the act are yet unknown.

A series of electoral-related violent acts were carried out throughout Mexico in preceding days. On Monday public facilities were attacked with explosives in the states of Puebla and Veracruz. The bombing caused no fatalities or injuries. The first explosive attack took place in Puebla at the offices of the National Electoral Institute, the Urban Transportation Network (RUTA) and the Economy Secretary. The bombs caused the destruction of windows, doors and furniture. In Veracruz, two offices from the secretary of Social Development were attacked by people with Molotov cocktails. People also lit fire to a local office of the National Electoral Institute in the city.
