Saudi Gazette report

RIYADH — Warning sirens will sound over the capital and adjoining cities on Thursday as the General Directorate of Civil Defense plans tests on its public alarm system.

The test, which will also take place in Ad-Dilam, Diriyah and Khafji, are being carried out to ensure the sirens are effective and ready, Directorate of Civil Defense spokesman in Riyadh, Lt. Col. Mohammed Al-Hammadi, said.

The tests come as Saudi Arabia — backed by world powers — investigates this week’s attacks on the Aramco oil facilities.

The Saudi Aramco facilities were hit in drone strikes earlier this week, causing fires to break out.

The Houthis claimed responsibility, but the United States believes the attacks originated in southwestern Iran, a US official told Reuters, an assessment that further increases tension in the Middle East.

In response, Iran issued a denial, warning it would respond to any attacks.
