A group of United Nations experts on Tuesday condemned US President Donald Trump’s recent threats to wage war on Venezuela and said his decision to bomb at least seven boats in international waters—killing dozens of people accused without evidence of drug trafficking—amounted to “extrajudicial executions.”

Trump’s repeated threats against Venezuela “violate the fundamental international obligations not to intervene in the domestic affairs or threaten to use armed force against another country,” said the trio of experts, warning that the US president’s belligerence represents “an extremely dangerous escalation with grave implications for peace and security in the Caribbean region.”
