Mexico City: Protesters angry at the alleged massacre of 43 missing Mexican students blocked access to Acapulco`s airport on Monday in the latest demonstration over a case that has repulsed the nation.
Thousands of people marched to the Pacific resort`s international airport, with parents of the students leading the demonstration along with comrades from the 43 young men`s teacher-training college in the southern state of Guerrero.
"Nobody goes in, nobody goes out until further instructions," a masked student, who blocked the entrance with seven other protesters armed with sticks, told AFP.
Felipe de la Cruz, a spokesman for the families of the 43 students, said they would prevent access to the international airport for three hours.
Before reaching the airport, a group of masked protesters clashed with riot police who had tried to block their way, injuring 11 officers, a public security official said. After negotiations, the protesters were allowed to go through.
Many protesters were armed with bats, metal pipes and machetes amid anger over a case that has turned into the biggest crisis of President Enrique Pena Nieto`s administration.
"Pena out! Pena murderer! Stay in China," they chanted, referring to the president`s controversial decision to travel to a summit in China amid public fury over the crime.
Tourists had to reach the airport by foot, pulling their suitcases behind them.
On Saturday, thousands of people marched in Mexico City, where a group of 20 protesters briefly set fire to the door of the National Palace, which Pena Nieto uses for official ceremonies.The demonstrations came after authorities announced Friday that gang suspects confessed to killing the 43 students, incinerating their remains and tossing them in a river after receiving them from corrupt police.
But Attorney General Jesus Murillo Karam downplayed chances of ever identifying the charred remains, warning that only two bones were salvageable for DNA tests.
Authorities say gang-linked police shot at busloads of students in the Guerrero city of Iguala on September 26, in a night of violence that left six people dead.
The police then handed the 43 abducted students to the Guerreros Unidos drug gang, prosecutors say.
Authorities say Iguala`s mayor ordered police to confront the students over fears they would interrupt a speech by his wife, who headed the local child protection agency.
The students had traveled to Iguala to raise funds but hijacked four buses to return home, a common practice among the young men known for their radical leftwing politics.
Officials stopped short of declaring the students dead, stressing that they were waiting for DNA results.
Murillo Karam said experts indicated that there were "two remains, only a kneecap and another piece, that have a possibility" of being matched to DNA samples.
The two pieces will be sent to a lab, which "did not tell us that it could (identify them) but (said) that there was a possibility," he told the Televisa network.
The government has sought the assistance of experts from Austria`s Innsbruck University.Parents of the 43 students, who deeply distrust the government, say they will only believe their sons are dead once they get DNA test results from independent Argentine forensic specialists.
"We want the government to do everything possible as soon as possible to find the boys alive, because they are deceiving us," said Carlos Ivan, father of one of the missing students.
Pena Nieto was in China on Monday for an Asia-Pacific Economic Cooperation (APEC) summit after brushing aside criticism over his decision to travel amid the human rights crisis.
