At least seven explosions were heard early Saturday in Venezuela’s capital, Caracas, amid escalating tensions with the United States. Media reports described black smoke rising from several parts of the city and low-flying aircraft overhead, prompting residents to rush into the streets. Videos circulating on social media showed smoke plumes and air raid sirens across the city.

Colombian President Gustavo Petro claimed that Venezuela had come under attack and called for United Nations intervention. Venezuelan President Nicolás Maduro said he was ready to discuss drug trafficking issues with the United States but accused Washington of using sanctions and military pressure to try to overthrow his government and seize the country’s vast oil reserves. The Associated Press and Reuters both confirmed reports of multiple explosions and aircraft activity.

The incidents come as the United States continues maritime operations against drug trafficking in the Caribbean Sea and the Pacific Ocean, where 115 people have reportedly been killed in recent attacks.
