A limited fire broke out Tuesday in an administrative building at Aramco, one of the world's largest oil facilities, that was targeted in an attack in the country's Eastern Province, Saudi Arabia's Ministry of Energy said. The ministry said no injuries were reported.

The attack came as the Iranian-backed Houthis and the Saudi coalition fighting them exchanged attacks Tuesday night. The fighting marked a fresh escalation in the widening Middle East crisis and came shortly after the Saudi coalition reported a series of alerts for incoming missiles heading for the Eastern Province, a major oil-producing region, and the capital Riyadh.
