Hundreds of people have taken to the streets in the Mexican state of Guerrero to protest against the suspected massacre of 43 students, PressTV reported.
During a rally in Chilpancingo, the capital city of the southern state of Guerrero, the angry protesters clashed with the Mexican riot police and set fire to the regional headquarters of the Institutional Revolutionary Party (PRI), the country's ruling party.
Three police officers and two journalists were injured during the clashes.
"The vandalistic assault on our building is more than an attack against this political party. It is an aggression against Guerrero's society and represents a threat to people that should not be repeated or left unpunished," the PRI said.
Meanwhile, Manuel Martinez, a spokesman for the families of the missing students, vowed to continue anti-government protests after his unavailing talks with the Mexican interior minister and attorney general.
"We are tired of the same speeches. We want the 43 back alive," said Martinez, adding, "The protests will continue. We will take away the powers of the political parties."
On September 26, 43 students, all trainee teachers, disappeared in the city of Iguala in the state of Guerrero following an attack by police forces suspected of having links to drug gangs. The incident took place during a protest rally over teachers' rights.
The recent protests came after authorities announced last week that three detained gang members had confessed to the killing of the students and burning their bodies.
The gang members have claimed in their confessions that the police had handed over the students to them.
