Multiple explosions shook Caracas, Venezuela’s capital city, on Saturday, though the origin of the blasts remained uncertain in the immediate aftermath.

The incidents occurred against a backdrop of escalating friction between Washington and Caracas. For months, the Trump administration has intensified its campaign against Nicolás Maduro, Venezuela’s authoritarian leader. U.S. officials have leveled accusations of narcotics trafficking against Maduro’s government, with the State Department going so far as to characterize Venezuela as a “narco-terrorist” regime.

Colombian President Gustavo Petro, who has been openly critical of Trump administration policies, took to social media with an urgent message: “Right now they are bombing Caracas. Alert to the whole world, they have attacked Venezuela. They are bombing with missiles.” However, no verification or physical evidence has emerged to confirm that military strikes caused the explosions.

When questioned about the situation, a U.S. military spokesperson in Washington confirmed awareness of the explosion reports but declined to comment on whether American forces were involved.

The lack of clarity about what triggered the blasts has left the situation shrouded in uncertainty as regional leaders and international observers await further information.
