In Venezuela, security forces 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 for 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.
