Ministers from the Organization of American States failed Monday to agree on a resolution to address the crisis in Venezuela, as the death toll from weeks of clashes at anti-government protests rose to 74.

Meanwhile, as the OAS opened its annual general assembly in Mexico, foreign ministers from the 34-nation regional group scrambled to adopt a joint response to the crisis -- and came up short.

Since April 1, after Venezuela's Supreme Court tried to strip the powers of the opposition-majority legislature, the country has descended into running street battles between anti-government protesters and Maduro's security forces and supporters.

Maduro's opponents accuse the president of clinging to power by repressing opponents, eradicating checks and balances, and seeking to write a new constitution.

Violent scenes played out again Monday, as riot police and soldiers used tear gas and water cannons to block demonstrators from marching on central Caracas.

A 17-year-old boy was shot in the chest and killed in Altamira on the capital's east side, while six others were wounded by bullets, officials said.
