In Venezuela, National Guard troops used tear gas and water cannons Thursday as antigovernment protesters marched on the Interior Ministry in the capital Caracas. Across town, medical workers evacuated three newborns and one pregnant woman in labor from a maternity hospital besieged by opposition protesters. It was the latest violence that’s seen 53 people killed in protests since opponents of President Nicolás Maduro took to the streets demanding an early election. In Washington, President Trump said the U.S. could intervene in Venezuela’s political crisis.

President Donald Trump: “We will be working with Colombia and other countries on the Venezuela problem. It is a very, very horrible problem. And from a humanitarian standpoint, it is like nothing we’ve seen in quite a long time.”

On Thursday, the Trump administration announced sanctions against eight members of Venezuela’s Supreme Court, after they ruled in January that opposition party members were in contempt of the constitution and removed them from power. President Maduro has accused the U.S. of supporting an attempt by opposition parties to mount a coup.
