New: Mexico insists 43 missing students are dead.

A policeman has shot dead a teenage boy during an anti-government protest in Venezuela.
Chaotic scenes broke out in the western city of San Cristobal, as 20 people clashed with police in a demonstration over political unrest and the country's worsening economic crisis.

But a 14-year-old boy was caught up in the violence, and a police officer has confessed to shooting him with a rubber bullet.

The head of the citizen security said the teen died in confusing circumstances and the police officer has been arrested.

The Venezuelan president has also condemned the violence.

“Some policemen went past there. A fight broke out, the police said they were surrounded and attacked with stones, and one of the police fired his shotgun and this boy was killed. I condemn this killing and I order an investigation in the capture of those responsible. This is how it happened and those responsible for this killing are behind bars.”

Officials said the boy died on his way to hospital.
