US President Donald Trump has called off efforts to reach a diplomatic agreement with Venezuela and told his special envoy Richard Grenell to stop all outreach, a senior US official said on Monday.

Axar.az informs, citing Reuters, the news, which was first reported by the New York Times, follows a series of military strikes on vessels carrying drugs near Venezuela. Trump told Congress that the US is engaged in “a non-international armed conflict” with drug cartels.

Although Trump is reportedly considering strikes inside the South American country, the US official told Reuters that the president has not yet determined whether to advance his military campaign to a second phase.

Trump delivered the message to Grenell during a meeting in the Oval Office last Thursday with senior military leaders, the senior official said.

Trump on Sunday told US service members that US strikes on vessels off the coast of Venezuela had halted the flow of drugs by sea and the US would now “have to start looking about the land.” No further details were released by the White House.
