The CIA conducted a drone strike on a port facility in Venezuela last week, according to people briefed on the operation, a development that suggests an aggressive new phase of the Trump administration’s pressure campaign against the Maduro government has begun.

The strike was on a dock where U.S. officials believe a gang was storing narcotics and potentially preparing to move the drugs onto boats. The strike is the first known U.S. operation inside Venezuela.

The attack last week, on a dock purportedly used for shipping narcotics, did not kill anyone, people briefed on the operation said. But it was the first known U.S. operation inside Venezuela.
