US Secretary of State Mike Pompeo has promised more sanctions against the embattled government of Venezuelan leader Nicolas Maduro. Neighboring countries are set to demand a firm response to Maduro's aid blockade.
Commenting on the clashes between soldiers and activists trying to deliver food and other emergency supplies into Venezuela, US Secretary of State Mike Pompeo said Washington would continue to pressure Maduro until he understood his days were "numbered."
Pompeo blamed the border violence on armed loyalists known as "colectivos," and told CNN that more sanctions were an option.
Pompeo said Washington would seek "other ways" to get food aid to Venezuelans after Maduro shut the borders leading to violence that saw two people killed and 300 others injured.
Brazil's Foreign Minister Ernesto Araujo also hit out at Saturday's bloody violence, describing it as "a criminal act committed by the Maduro regime."
Colombian President Ivan Duque, meanwhile, denounced the "barbarity and violence" at his country's border, where hundreds of volunteers attempted to offload aid trucks and carry them into their poverty-stricken neighbor.
Stepping up pressure
Duque said a summit of regional governments in Bogota on Monday would discuss "how to tighten the diplomatic siege of the dictatorship in Venezuela."
Maduro severed diplomatic relations with Colombia on Saturday over the aid trucks standoff and gave its diplomats 24 hours to leave the country.
Guaido, meanwhile, urged foreign powers to consider "all options" in ousting Maduro, ahead of Monday's talks, where he is also due to meet US Vice President Mike Pence.
On Saturday, trucks laden with food and medicine repeatedly attempted to push past lines of troops on the Colombian border but were met with tear gas and rubber rounds. Two of the aid trucks went up in flames.
Colombian immigration authorities said more than 100 Venezuelan soldiers had deserted and crossed into the country.
Officials in the Brazilian border state of Roraima said Sunday that the number of Venezuelans being treated for gunshot wounds had risen to 18. Armed men launched gun battles in the Venezuelan border town of Santa Elena on Saturday, where aid trucks also gathered.
