DUBAI, United Arab Emirates (AP) — Saudi Arabia says it is joining a U.S.-led coalition to secure the Mideast's waterways after an attack targeting its crucial oil industry.

The state-run Saudi Press Agency carried a statement Wednesday morning quoting an unnamed official saying the kingdom had joined the International Maritime Security Construct.

That's a mission already joined by Australia, Bahrain and the United Kingdom.

The U.S. formed the coalition after attacks on oil tankers that American officials blame on Iran, as well as Iran's seizure of tankers in the region. Iran denies being behind the tanker explosions.

The U.S. military did not immediately respond to a request for comment.

On Saturday, an attack struck the world's biggest oil processing facility in Saudi Arabia.
