Thousands of people have taken part in demonstrations in Mexico City to demand a full investigation into the disappearance of 43 students four months ago, the BBC reported.

The trainee teachers went missing after taking part in a protest in the south-western town of Iguala on 26 September.

Prosecutors say they were seized by local police and handed over to a local gang, which killed them.

Those marching included the families of the missing students.

They started their journey from four different suburbs of Mexico City and headed to the city's main square, the Zocalo.

More than 100,000 people have been killed or have disappeared in Mexico.

But the BBC's Katy Watson says the case of the 43 students has galvanised Mexicans angry with high levels of corruption and collusion between local authorities, police and criminal gangs.
Relatives of the 43 trainee teachers are sceptical about the official version for their disappearance.

"We will carry on fighting until we find them, until the end," Macedonia Torres, the mother of one the missing students, told Grupo Formula radio.

"I don't believe they are dead. And if they are dead we will hold the government responsible," added Maximino Hernandez, father of Carlos Lorenzo Hernandez.
