Activists also threw stones at the security forces, who responded with tear gas. The troops also prepared water cannons to prevent possible illegal border crossings.
Meanwhile, the Venezuelan National Guard has started to deploy additional forces to the Simon Bolivar Bridge on the country's western border with Colombia amid continued clashes between the security forces and protesters, a Sputnik correspondent reported.
Clashes on the Venezuelan-Colombian border erupted on Saturday amid attempts to bring in unauthorized aid into Venezuela. Venezuelan President Nicolas Maduro has said he believes that the aid deliveries are a ploy to topple his government, while Venezuelan Vice President Delcy Rodriguez has dismissed allegations about a humanitarian crisis in the country and recalled that international law provided for deliveries of foreign humanitarian aid only in cases of natural disasters and armed conflicts.
Meanwhile, US Vice President Mike Pence said during a Lima Group meeting on Monday that Washington would continue its efforts to deliver humanitarian assistance to Venezuela and would provide an additional $56 million to US partners in the region. Pence also said that the US is planning to announce new sanctions against Venezuela's government in coming days.
However, the United Nations and the Red Cross have urged Washington not to politicize humanitarian assistance and not to deliver any aid without the consent of the Venezuelan government.
Mexico and Uruguay have refused to recognize Guaido, declaring themselves neutral and promoting crisis settlement via dialogue.
