U.S. forces boarded a Venezuela-linked oil tanker sanctioned by Washington in the North Atlantic after tracking the vessel for several weeks, a U.S. official said.

The official spoke to The Associated Press on Wednesday on the condition of anonymity to discuss sensitive military operations. The official said the U.S. military seized the vessel and handed over control to law enforcement officials.

The U.S. had been pursuing the tanker since last month after it tried to evade a U.S. blockade on sanctioned oil vessels around Venezuela.

In a post to social media, U.S. European Command confirmed that the U.S. Coast Guard cutter Munro tracked the ship ahead of its seizure "pursuant to a warrant issued by a U.S. federal court.”

The military command went on to say that the seizure supported President Donald Trump’s proclamation on targeting sanctioned vessels that "threaten the security and stability of the Western Hemisphere.”
