Violence has erupted between police and masked anti-government protesters in Caracas, Venezuela.

Effigies of President Nicolas Maduro burned on the streets of the capital. Protesters threw petrol bombs at police, who responded with tear gas and water cannons.

More than 40 people – on both sides of the conflict – have been killed in violent protests since February.
