Explosions were reported in Venezuela’s capital of Caracas on Saturday. It was not immediately clear what caused the blasts.

The explosions in the country came after months of threats, warnings and accusations of drug smuggling from President Trump and the U.S. government, all aimed at Venezuela’s authoritarian president, Nicolás Maduro, whom the State Department has branded the head of a “narco-terrorist” state.

Top Trump aides have pushed to oust Mr. Maduro, a self-described socialist who has led Venezuela since 2013. U.S. officials have called him an illegitimate leader and have accused him of controlling criminal groups tied to drug trafficking, charges he denies.
