Mexico missing students: Capital sees mass protests
Relatives of 43 missing Mexican students, who the authorities say were murdered by a drugs gang, have led mass protests in the capital, the BBC reported.
The marches were largely peaceful but some protesters clashed with police near the presidential palace.
Convoys carrying the families arrived in Mexico City on Thursday after touring the country to rally support.
Many remain unconvinced by the official explanation for the students' disappearance and hope they are alive.
Masked protesters clashed with police near the airport hours before the three marches started.
Francisco Lagro, father of 19-year-old Magdaleno, one of those missing, was travelling on one of the caravans.
"It's been almost two months without knowing where they are. We don't know anything and we're desperate," he said.
"What are they doing? In what conditions? Do they get any water or food? Are they tied up? We have so many questions."
