VENEZUELA-Security forces in Venezuela have used tear gas to break up a student demonstration in the capital, Caracas.

Hundreds of protesters were demanding the release of fellow students detained during two weeks of unrest, and called a fresh march for Sunday.

In another part of Caracas, a large pro-government march was held.

Earlier this week, President Nicolas Maduro declared an early start to the week-long Carnival public holiday in an attempt to end the unrest.

On Monday, Venezuela's Attorney General Luisa Ortega said 13 people had died in the violence, although President Maduro put the figure of protest-related deaths at more than 50 on Wednesday.
