Explosions and low-flying planes are heard in Venezuelan capital Caracas

At least seven explosions were heard, along with low-flying planes, in Venezuela’s capital Caracas around 2 a.m. local time on Saturday. Residents from different neighborhoods rushed to the streets. Some could be seen in the distance from various areas of Caracas.

Trump administration officials said they were aware of reports of explosions and planes, sources told CBS News, but there was no immediate response to requests for comment from the White House or any immediate reaction from the Venezuelan government.

President Gustavo Petro of neighboring Colombia said in a post on social media that someone was “bombing Caracas right now,” without saying who.

“Alert the whole world, they attacked Venezuela by bombing with missiles,” he said, calling for a United Nations meeting.

The reported explosions come after months of the U.S. military targeting suspected drug-trafficking boats in the region and as the Trump administration puts pressure on Venezuelan President Nicolás Maduro. Thousands of U.S. forces and several warships have been deployed to the region, and President Trump has been hinting for weeks at the possibility of a broader military operation.

The Trump administration has accused the Maduro regime of collaborating with drug traffickers, something the Venezuelan government denies. The United States has also put pressure on Venezuela’s oil sector, seizing two sanctioned tankers last month. Mr. Trump announcement a “total and complete blockade” of all sanctioned oil tankers entering or leaving Venezuela by mid-December.

On Friday, Venezuela said it was open to negotiating an agreement with the United States to combat drug trafficking. Maduro also said in a pre-recorded interview broadcast Thursday that the United States wanted to force a change of government in Venezuela and gain access to its vast oil reserves.

Mr. Trump has not explicitly stated what his goal is for Venezuela, but said late last month that it would be “smart” for Maduro to leave power. He also warned that if Maduro “plays hard, this will be the last time he can play hard.”
