Mexico is breaking diplomatic ties with Ecuador after police raided its embassy in Quito to arrest former Ecuadorian Vice President Jorge Glas.

Confirming the move in a statement to CNNE, a foreign ministry spokesperson said that all Mexican diplomatic staff would leave Ecuador immediately

Ecuadorian police stormed the Mexican embassy in Ecuador’s capital Quito on Friday night to arrest the former vice president, who is seeking asylum there, an escalation of tensions that Mexico decried as “an outrage against international law.”

Video from the scene showed police officers massing around the embassy, some armed. Embassies are generally considered as protected spaces under diplomatic norms.
