The US could expand military operations against state-linked drug cartels, the president has said

President Donald Trump has signaled that the US could soon extend its military campaign against drug smuggling groups it links to Venezuela from the sea to land operations.

Speaking at a press conference on Thursday, Trump touted what he described as great success in intercepting alleged Venezuelan state-linked "drug boats." "Drugs coming in by sea are like 5% of what they were a year ago," he said.

"The land is going to be next," he added, without elaborating on where and when potential attacks could take place.

Trump also pushed back against the notion that he needs a congressional war declaration for strikes on alleged narcotraffickers. "We may go to the Senate; we may go to the Congress and tell them about it, but I can't imagine they'd have any problem with it," he said.

In recent weeks, US naval and air operations have struck what Washington says are Venezuelan-linked drug boats in the Caribbean and Pacific, killing dozens of people. Caracas denies any state role in narcotics trafficking and accuses Washington of seeking "regime change."

Tensions rose further after Trump said last week that he had authorized covert CIA activity inside Venezuela. President Nicolas Maduro described the public acknowledgment as unprecedented and "desperate" while putting the military on heightened alert. He also warned that Venezuela maintains a large arsenal of Soviet-era Igla-S air defense systems.

Meanwhile, on Thursday, the Wall Street Journal reported, citing sources, that two nuclear-capable US Air Force B-1 bombers flew near Venezuelan airspace. Trump, however, has dismissed the claim while acknowledging that "we're not happy with Venezuela."
