Colombia announced the move after US President Donald Trump called President Gustavo Petro an ‘illegal drug leader’.

Colombia has said it has recalled its ambassador to the United States, after US President Donald Trump threatened to cut off aid and made disparaging remarks about the Colombian president over the weekend.

The South American country’s Ministry of Foreign Affairs said on Monday that Ambassador Daniel Garcia-Pena had already arrived in Bogota to meet with President Gustavo Petro, whom Trump called an “illegal drug leader” on Sunday.

The growing feud between the two countries has centred on US strikes in the Caribbean on vessels that the Trump administration alleges are transporting drugs, mostly from Venezuela. Those strikes, which have killed dozens of people and are widely viewed as a violation of US and international law, have drawn strong criticism from Petro.

In a social media post on Sunday, Trump said aid to Colombia would be cut off and threatened that if Petro did not take more steps to combat the drug trafficking in the country, the US would do the task itself, “and it won’t be done nicely”.

Colombian Interior Minister Armando Benedetti said on Monday that he viewed those remarks as “a threat of invasion or military action against Colombia”.

“I can’t imagine closing down some hectares [of drug production sites] unless it’s in that way, unless it’s by invading,” he added.

The US also announced over the weekend that it had struck a vessel from Colombia on Friday, alleging that it was helmed by a left-wing rebel group involved in the transport of drugs. The Trump administration has not provided evidence regarding those claims.

Petro responded in a series of social media posts, stating that one of those killed in the attack was a Colombian fisherman named Alejandro Carranza, who did not have any ties to drug trafficking.

“US government officials have committed murder and violated our sovereignty in territorial waters,” he wrote.
