The government of Ecuador has condemned what it described as an attempt by a US federal immigration agent to enter the Ecuadorean consulate in Minneapolis.
The agent was prevented from gaining access by consular officials, who acted "to guarantee the protection of the Ecuadoreans who were inside the consulate at the time", a statement by Ecuador's foreign ministry said.
Ecuador, whose president is an ally of Trump, has filed an official complaint.
The incident comes at a time of high tension in the US city, just days after intensive care nurse Alex Pretti was shot dead by border agents during protests against the Trump administration's immigration crackdown in Minneapolis.
Ecuador's foreign ministry said in a statement that an agent of the US Immigration and Customs Enforcement agency (ICE) had "tried to enter the premises of the consulate" at 11:00 local time (17:00 GMT) on Tuesday.
