The UAE Ministry of Foreign Affairs Monday May 18 formally condemned the Sunday Barakah drone strike as a "dangerous escalation" and "unacceptable act of aggression", reserving the right to respond - but notably did NOT name Iran directly in its formal statement, contrast with previous Iran-on-UAE attacks where UAE has named Iran. The UAE has opened an investigation into drone source and is working on whether the Iranian military or one of its proxies bears responsibility - more restrained than the Monday-morning escalation framing implied.
