The Venezuelan opposition leader and self – proclaimed president, Juan Guaido, said last week that Cucuta was one of three collection points for international aid.
His move has intensified tensions with the Maduro government, while many in Venezuela are in desperate need of such supplies.
Friday, he tweeted: "Humanitarian aid is a show to humiliate us and to justify the military aggression, a macabre plan that does not hide the theft of more than 10 billion dollars of our country by the United States. If they want to help, they must put an end to the blockade, persecution and aggression against Venezuela. "
Help route blocked
Guaido said Thursday that he was confident in the success of his efforts to bring humanitarian aid to the country.
"We will succeed in letting humanitarian aid go because it is about saving lives," Guaido said on his official Twitter feed. "As we work every day to deliver humanitarian aid, they insist on diverting medicines and food from those in urgent need."
Colombian officials and a Good King News photojournalist at the scene confirmed the blockade, which would effectively prevent humanitarian aid from reaching Venezuela by this route.
The images show an orange tanker and two large blue containers positioned in the middle of the Tienditas three-lane bridge, which connects Cucuta to the city of San Antonio in the state of Tachira, in western Venezuela.
Juan Caicedo, a spokesman for Migration Colombia, of the Colombian Ministry of Immigration and Immigration Control, said the Venezuelan army had put the blockade in place Tuesday afternoon, adding that surveillance cameras were monitoring the activity on the bridge.
US: Open the bridge
It is possible that the Venezuelan government is concerned that the aid that crosses the border may serve as a cover for an invasion aimed at deposing Maduro.
Guaido on Wednesday called on Venezuelan military officials – who until now were loyal to the government – to allow Colombia's aid to the country, led by a right-wing government criticizing Maduro.
"Brother, let the aid come in. Do not stop it," he said while addressing members of the country's armed forces at a meeting with farmers at Caracas. "The end of the usurpation will be the end of hunger," he added, calling on Venezuelans to reject the Maduro government.
US Secretary of State Mike Pompeo also urged Venezuela to open the bridge, saying that "the Maduro regime must allow help reach hungry populations".
Call for loyalty
Maduro has faced intense pressure since Guaido proclaimed himself acting president on Jan. 23, citing a constitutional ruler to open a rare challenge to Maduro's presidency.
The Venezuelan Foreign Ministry denounced any international support for Guaido, suggesting that European governments were acting as part of a US-led effort to overthrow Maduro, who had shown no signs of Abandonment of power.
On Thursday, Venezuelan Communications Minister Jorge Rodriguez said he presented a "proof" of what he called a coup attempt by the United States backed by the US against the Maduro government in January. .
Speaking live on television from the Miraflores Presidential Palace in Caracas, Rodriguez showed two alleged video confessions of military men involved in the plot and subsequently arrested by security forces.
Good King News has not been able to independently verify the authenticity of the video.
The two men described a plot led by an opposition member, Julio Borges, a former president of the National Assembly of Venezuela living in Bogota.
According to Rodriguez's re-enactment, Borges and other opposition leaders, with the help of the CIA, were organizing a military uprising in Caracas that was discovered and blocked by security forces Venezuelan women on 21 January.
Maduro responded Wednesday to a tweet from US National Security Advisor John Bolton, who said that "any senior Venezuelan officer who defends democracy and recognizes the constitutional government of President Juan Guaido" would not be the object of US sanctions.
Speaking during military exercises, Maduro called on the Venezuelan military to remain loyal and ordered the armed forces to defend the Venezuelan territory.
"Is John Bolton the military leader of Venezuela? Listen to John Bolton, here is the response of the armed forces to your so-called coup coupeurs. Let's say our slogan out loud," Loyal Always, Never Traitors "so that we can hear it in Washington.," He said.
Maduro also welcomed a meeting of the international contact group on Venezuela in the Uruguayan capital, Montevideo, on Thursday: "We are ready and ready to participate in a process of constitutional and sovereign dialogue".
The contact group includes Bolivia, Costa Rica, Ecuador, France, Germany, Italy, Netherlands, Portugal, Spain, Sweden, United Kingdom and co-organizer of Uruguay.
International Assistance Commitments
Guaido identified the three collection points of international humanitarian aid as the Brazil-Venezuela border, an unidentified Caribbean island, and Cucuta. However, it is unclear whether assistance will be provided by any of these pathways.
On Monday, Canada hosted a meeting of the Lima Group regional bloc to discuss how the international community can further assist the people of Venezuela, including through immediate humanitarian assistance.
In opening a session in Ottawa, Prime Minister Justin Trudeau announced a contribution of $ 53 million ($ 40.4 million) to Venezuela.
German Foreign Minister Heiko Maas also said that Germany has allocated an aid of 5 million euros (5.72 million dollars) to Venezuela. Later Monday, Guaido said that Germany had promised 6 million euros ($ 6.86 million).
USAID began packing food pallets after the announcement of the shipment of humanitarian aid by Bolton last week.
Guaido called the situation "emergency … crisis" and said that humanitarian aid would begin to flow to Venezuela in the coming days, defying Maduro's repeated refusal to deal with the shortage of food and medicine.
He presented this initiative as part of a plan to get the military to cooperate with the opposition.
