Security forces in Venezuela have dispersed an anti-government march opposition leader Juan Guaido led, his first since he returned from an international tour.

Guaido is trying to revive a campaign to remove President Nicolas Maduro as the country's economic crisis deepens.

At the United Nations, the High Commissioner for Human Rights said Venezuela’s security forces were using increasing levels of violence against opposition supporters.
