The attackers also hurled stones and sticks at the National Guard officers, which, in turn, used tear gas.

Some tear gas grenades hit the territory of Brazil, which prompted the protesters to demand that the Brazilian military take action.

The report comes as the Venezuelan opposition led by self-proclaimed president Juan Guaido was seeking to ensure deliveries of the US-sponsored humanitarian aid to the country via neighboring Brazil and Colombia on Saturday, which resulted in numerous clashes.

Amid the opposition's attempts to force unauthorized aid deliveries into the country, the legitimate president, Nicolas Maduro, severed diplomatic and political relations with Colombia, while the Venezuelan Foreign Ministry announced that Colombian diplomats must leave the country in 24 hours.

Maduro, who slammed the aid deliveries as a ploy to topple his government, previously closed the land border with Brazil and the sea border with the Lesser Antilles and then shut several border crossings with Colombia.

Bogota announces decision to turn back trucks with humanitarian aid for Venezuela

Mexico City: Colombian Foreign Minister Carlos Holmes Trujillo said that President Ivan Duque Marquez had ordered trucks with humanitarian aid, which departed for Venezuela to return to the country.

"The trucks with humanitarian aid, with the exception of those that were burned, have been ordered to return," Holmes Trujillo said at a press conference in the Colombian border city of Cucuta on Saturday.

According to the minister, the vehicles will return to the aid collection center in Cucuta.

"Colombia and the international community acted peacefully and received in response violence from the Maduro regime," he added.

Earlier on Saturday, the Venezuelan opposition led by self-proclaimed interim president Juan Guaido sought to ensure deliveries of the US-sponsored humanitarian aid to the country via neighboring Brazil and Colombia, which resulted in numerous clashes. During one of the attempts to cross into Venezuela, several trucks with aid were burnt at the bridge connecting Cucuta and Venezuela.

Venezuelan President Nicolas Maduro refuses to allow in unauthorized aid deliveries, saying that they are a ploy to topple his government. Amid Saturday's attempts to force unauthorized aid deliveries into the country, Caracas severed diplomatic and political relations with Colombia, while the Venezuelan Foreign Ministry announced that Colombian diplomats must leave the country in 24 hours.

Venezuelan Vice President Delcy Rodriguez previously recalled that under international humanitarian law, humanitarian aid is provided in the event of natural disasters, armed conflicts and war. According to Rodriguez, claims about the ongoing humanitarian crisis in the country are designed to justify the invasion of Venezuela, but the people will not allow this.

MEANWHILE.. People gather at New York's Wall Street to protest US 'imperialist' polices on Venezuela

Supporters of the Venezuelan government gathered at Wall Street in New York on Saturday, protesting what they call the US imperialism and possible military intervention in the Latin American country, a Sputnik correspondent reported from the scene.

The protesters have gathered in front of the Trump Building in Downtown Manhattan to demonstrate their support for President Nicolas Maduro, with their banners read: "Defend Venezuela against US imperialism," "Stop Trump’s Venezuelan coup," "End the sanctions," "Humanitarian aid is a Trojan horse."

The people also shouted "Hands off Venezuela," expressing their concern over attempts to intervene in Venezuelan internal affairs and force the unauthorized US humanitarian aid into the country.
According to the International Action Center, thousands of individuals from across the globe, including the United States, Canada, Australia, Azerbaijan, India, Italy, Iran and Mexico among other countries, have supported the call to take action on Saturday.

On Saturday, the Venezuelan opposition tried to ensure deliveries of the US-sponsored humanitarian aid to the country via neighboring Colombia and Brazil, which resulted in numerous clashes. Maduro previously warned that he would not allow in unauthorized aid deliveries, saying that they are a ploy to topple his government.

The situation in crisis-torn Venezuela escalated on January 23 when opposition leader Juan Guaido declared himself interim president and was immediately recognized by Washington, which prompted Maduro to accuse President Donald Trump's administration of trying to orchestrate a coup. Russia, China, Mexico, among other nations, have reaffirmed their support for Maduro as the country’s only legitimate head of state. In addition, the United Nations also still recognizes Maduro as Venezuela’s president.
