DUBAI (Reuters) - Yemen's Iran-aligned Houthi group attacked the United Arab Emirates in what it said was an operation using missiles and drones, setting off explosions in fuel trucks that killed three people and causing a fire near the airport of Abu Dhabi, capital of the region's commercial and tourism hub.

The strike on a leading Gulf Arab ally of the United States takes the war between the Houthi group and a Saudi-led coalition to a new level, and may hinder efforts to contain regional tensions as Washington and Tehran work to rescue a nuclear deal.
