Bogota-Colombian President Gustavo Petro has ordered the expulsion of all remaining Israeli diplomats after the Israeli navy intercepted a Gaza bound flotilla carrying international activists.

Petro’s office confirmed that two Colombian citizens were among those detained and demanded their immediate release. He wrote on X that the Colombians were “engaged in humanitarian activities in solidarity with Palestine,” and announced the suspension of Colombia’s free trade agreement with Israel.

The flotilla, which left Spain last month, included activists from more than 40 countries. Among those detained was Swedish climate activist Greta Thunberg. Israeli officials called the flotilla a “provocation,” claiming it was intended to support Hamas rather than deliver humanitarian aid.

The interception has drawn widespread criticism and triggered protests in several countries.

The diplomatic move comes just days after the United States revoked Petro’s visa, following his remarks at the UN General Assembly in New York urging American soldiers to “disobey” President Donald Trump’s orders.
