Ecuador’s minister of foreign affairs has filed a protest with the U.S. Embassy after Immigration and Customs Enforcement agents tried to enter the Ecuadorian consulate in Minneapolis without permission Tuesday.

A video of the attempt on social media shows a consulate staffer running to the door to turn the ICE agents away, telling them, “This is the Ecuadorian consulate. You’re not allowed to enter.”

One ICE officer can be heard responding by threatening to “grab” the staffer if he touched the agent before agreeing to leave.

International law generally prohibits law enforcement authorities from entering foreign consulates or embassies without permission, though sometimes permission may be assumed granted for life-threatening emergencies, like fires.
