Emergency workers rushed to search the rubble of collapsed buildings in and near the Venezuelan capital of Caracas on Thursday after back-to-back powerful earthquakes rocked the country, killing at least 164 people—a toll that's expected to reach the thousands as victims' bodies are recovered from the wreckage.The disaster began on Wednesday afternoon local time as a 7.2-magnitude earthquake hit around 100 miles west of Caracas. Just 39 seconds later, a 7.5-magnitude quake struck, compounding the damage. One Caracas resident told Reuters that the aftermath of the quakes "was like a horror movie."The Associated Press reported that rescue teams were seen "using power tools to work their way into piles of rubble where buildings once stood.""Panicked residents of the capital were sent pouring into the streets, and after the quakes many people walked among the debris searching for the missing among collapsed buildings and toppled electric poles," the outlet added. "Footage on state TV showed three children, covered in dust but alive, pulled from the rubble in La Guaira state... one of the areas hardest hit by the quakes because of the large number of collapsed buildings."Acting Venezuelan President Delcy Rodríguez, who took charge following the US abduction of President Nicolás Maduro in January, said that "dozens of buildings have collapsed" in La Guaira. "We are currently carrying out intensive rescue operations to save lives," Rodríguez added.US President Donald Trump, who authorized the illegal assault on Venezuela and kidnapping of Maduro earlier this year, wrote on social media that his administration "stands ready, willing, and able to help.""I have instructed all agencies of our government to get ready to move quickly," Trump wrote. "We will be there for our new and great friends. Early reports are not good!!!"Tom Fletcher, the United Nations' emergency relief coordinator, said in a statement Thursday that "we are fully mobilized to support the people of Venezuela following the deadly and devastating earthquakes that hit the country.""The coming days will require a massive collective effort to support the government-led response and help communities," Fletcher added. "Even before these earthquakes, nearly 8 million people in Venezuela were in need of humanitarian support. This disaster risks deepening existing vulnerabilities. Sustained international support for humanitarian organizations responding on the ground is essential and urgent."
