US, Venezuela spar at UN
The United States warned at the United Nations that Venezuela's crisis was worsening and could escalate into a civil conflict like that of Syria.
Following Security Council talks, US Ambassador Nikki Haley called for countries to send a message to Maduro.
"We've been down this road – with Syria, with North Korea, with South Sudan, with Burundi, with Burma," she told reporters. "The international community needs to say 'respect the human rights of your people' or this is going to go in the direction we've seen so many others go."
She earlier warned that Venezuela was "on the verge of humanitarian crisis."
Brazil's Defense Minister Raul Jungmann told reporters Wednesday his country was making contingency plans for a possible influx of Venezuelan migrants.
Venezuela's Foreign Minister Delcy Rodriguez, however, said on Twitter that the United States was out to topple the Venezuelan government.
"The United States has shed light on the plan it is leading to intervene in Venezuela," she said. "Other countries (at UN headquarters) put it loudly and clearly: Venezuela is no matter for the UN to address."
While the UNSC met, Maduro supporters gathered outside the presidential palace in Caracas. However, Maduro remained a no-show.
