The Venezuelan military has barricaded the Tienditas International Bridge, close to the border with Colombia, to stop aid coming into a country plagued by food and medicine shortages.
Dozens of volunteers prepared sacks of rice, canned tuna and protein-rich biscuits for malnourished children at a warehouse on the Colombian border on Friday as Venezuela's opposition vowed to deliver the US humanitarian aid to their troubled nation, even if it means mounting a mass mobilization of their countrymen to carry it in.
"The package is very nice on the outside: humanitarian aid".
Medina told a news conference at United Nations headquarters in NY: "I think we need the strength of the U.S., Brazil, Colombia". Mendoza reiterated that Maduro had been re-elected by a popular vote of 67.8 percent in last year's election, which the opposition coalition voluntarily boycotted, taking to the streets instead.
Guaido, who heads the opposition-led National Assembly, declared himself Venezuela's legitimate ruler on January 23.
China, Iran, Russia and Turkey have put their weight behind Maduro.
They want to invade and intervene in Venezuela - they say, as they said then - in the name of democracy and freedom.
The Trump administration last week issued sweeping sanctions against state oil company PDVSA, froze profits generated by refining subsidiary Citgo, and has vowed to starve Maduro's government of all revenue.
"It depends on what they're offering", Farnsworth said.
Guaido's representative in Cucuta, Lester Toledo, said the provisions already delivered were the "first drops" and promised "a tsunami of humanitarian aid" would follow.
"We're going to open a humanitarian corridor and the doors to freedom", he told journalists.
He claims his legitimacy from the constitution, but Maduro - labeled a dictator by the West and his Latin American neighbors - insists his re-election a year ago was constitutional.
National Assembly leader Guaido told AFP he would do "everything that is necessary.to save human lives", acknowledging that USA intervention is "a very controversial subject".
"Liberate the money that has been blocked and sequestered", said Maduro, who has repeatedly accused the USA of fomenting a coup.
Maduro said he was willing to meet with envoys of the so-called International Contact Group, that is backed by the European Union, but said a statement from its first meeting on Thursday was partisan and ideological. "You're deaf... They've taken extremist positions".
Asked what would happen if the Venezuelan military blocks the aid from going in, Whitaker said any obstacles would be dealt with as they arise and reiterated that Trump has made clear nothing is off the table - though, he added, the priority is to arrange a broad global mission.
Leftist-led Bolivia also refused to support snap presidential elections in Venezuela.
