Several explosions heard in Venezuela’s capital city of Caracas

ABC:

Several explosions were heard around 2 a.m. local time in Venezuela’s capital city of Caracas, witnesses said, and photos and videos showed plumes of smoke and a large fireball in the night sky.

This comes amid rising tensions between the U.S. and Venezuela including a build-up of U.S. military forces in the Caribbean and the targeting of alleged drug-smuggling boats.

Meanwhile, the Federal Aviation Administration has issued an alert prohibiting U.S. civil aircraft from flying over Venezuela “due to safety-of-flight risks associated with ongoing military activity,” according to the FAA.

There was no immediate confirmation from U.S. officials regarding any U.S. action.
