• US forces attacked vessel linked to Colombian group, says Hegseth.
• Trump accuses Petro of backing drug production, halts US payments.
• US-Colombia relations strained over military actions, visa revocation.

US forces attacked a vessel associated with a Colombian leftist rebel group, Defence Secretary Pete Hegseth said on Sunday, the same day President Donald Trump called Colombian President Gustavo Petro an “illegal drug leader” and said payments to the South American nation would cease.

Trump’s comments marked a new low in relations between Bogota and Washington, which have frayed since Trump returned to office in January and since his administration launched a series of strikes on vessels allegedly transporting drugs in the Caribbean.

Hegseth wrote on X that the Pentagon had destroyed a vessel and killed three people on Friday “in the USSOUTHCOM area of responsibility,” which includes the Caribbean.

He said the ship was affiliated with the leftist rebel group National Liberation Army and was involved in illicit narcotics smuggling, without offering evidence to back the claim.

The Pentagon said it had nothing to add beyond Hegseth’s initial post.

Colombia condemns Trump’s remarks

Colombia’s Foreign Ministry condemned Trump’s remarks as offensive and a direct threat to its sovereignty, and vowed to seek international support in defence of Petro and the country’s autonomy.

“These accusations represent an extremely serious act and undermine the dignity of the president of Colombians,” it said in a statement.

The post from Hegseth came hours after Trump lambasted Petro on social media and said the United States would stop large-scale payments and subsidies to Colombia.

“President Gustavo Petro, of Colombia, is an illegal drug leader strongly encouraging the massive production of drugs, in big and small fields, all over Colombia,” Trump wrote on Truth Social.

“The purpose of this drug production is the sale of massive amounts of product into the United States, causing death, destruction, and havoc,” Trump wrote.

Reuters could not immediately establish which payments Trump was referring to. Colombia was once among the largest recipients of US aid in the Western Hemisphere. Still, the flow of money was suddenly curtailed this year by the shuttering of USAID, the US government’s humanitarian assistance arm.

The US State Department referred questions to the White House, which did not immediately respond to a query.

Fraught relations

Last month, the United States revoked Petro’s visa after he joined a pro-Palestinian demonstration in New York and urged US soldiers to disobey Trump’s orders.

The US administration’s deadly strikes on boats in the Caribbean have also outraged Colombians. Many legal experts and human rights activists have condemned the extraordinary series of military actions, with Amnesty International describing it as murder on the high seas.

Earlier this month, Petro said one of the strikes hit a Colombian vessel, an allegation the Trump administration denied.

Petro condemned the most recent bombing, saying the boat belonged to a “humble family”, not the National Liberation Army. He also hit back at Trump’s remarks.

“Mr Trump, Colombia has never been rude to the United States… but you are rude and ignorant to Colombia,” Petro responded on X. “Since I am not a businessman, I am even less a drug trafficker. There is no greed in my heart.”

Colombia is fighting its own longstanding drug problems. Last year, Petro pledged to tame coca-growing regions in the country with massive social and military intervention, but the strategy has brought little success.

In September, Trump designated countries such as Afghanistan, Bolivia, Burma, Colombia and Venezuela among those the United States believes to have “failed demonstrably” in upholding counternarcotics agreements during the past year.
