NEW YORK — The United States announced Thursday it would revoke the visa of Colombian President Gustavo Petro, hours after he used his UN General Assembly address to accuse Washington of complicity in what he called genocide in Gaza. The State Department confirmed the decision in a statement.

Petro, Colombia's first leftist president, has clashed repeatedly with the Trump administration over migration, drug-eradication policy and Middle East diplomacy. His General Assembly speech in New York denounced US military aid to Israel and criticised American drug-interdiction operations in the Caribbean.

The visa revocation followed Petro's appearance at a pro-Palestinian rally near the UN complex, where he urged American soldiers to disobey orders. The State Department described his remarks as reckless and incendiary.

Bogotá's foreign ministry rejected the move as an attack on Colombian sovereignty and freedom of expression. The dispute deepens a rupture between the two governments that has already seen Washington decertify Colombia as a partner in counter-narcotics cooperation this year.

Petro, whose term ends in 2026, said on the social platform X that he did not need a US visa and would continue to speak against what he called imperial policies. Colombia's foreign ministry said it would summon the US chargé d'affaires in Bogotá.
