U.S. deploys weapons, troops to Saudi Arabia

WASHINGTON -- The U.S. is sending one Patriot missile battery and four ground-based radar systems to Saudi Arabia, the Pentagon said Thursday, in what officials describe as the first steps to help the kingdom protect itself against Iranian attacks.

Two more Patriot batteries and a THAAD missile defense system will be prepared to go later if needed, and the deployment will involve about 200 troops.

Military commanders and defense leaders have been working since last week to iron out what military aid to send to the region in response to what U.S. officials say was a brazen and unprecedented cruise missile and drone attack by Iran on Saudi oil facilities Sept. 14.

President Donald Trump during a White House meeting Sept. 20 put off, at least for now, any immediate military strike on Iran, but approved a broader effort to beef up security in Saudi Arabia and the region. He told reporters showing restraint "shows far more strength" than launching retaliatory strikes now.

The four Sentinel radar systems and the Patriot battery are designed to provide better surveillance coverage across northern Saudi Arabia. The bulk of the kingdom's Patriot batteries and other defenses are focused on the south to protect the country from attacks by Iranian-backed Houthis in Yemen. The Houthis launch almost daily attacks into Saudi Arabia and at times into the UAE.

Defense Secretary Mark Esper said last week additional security measures will be the first step, but he did not rule out additional moves down the road. Officials have said they are talking with allies in an effort to get more nations to contribute to security in the region.

"Other countries have called out Iranian misadventures in the region, and we look for them to contribute assets in an international effort to reinforce Saudi Arabia's defense," Pentagon spokesman Jonathan Hoffman said Thursday.

Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, said last week the goal is to defend Saudi Arabia against unconventional aerial attacks using a "layered system of defensive capabilities" that would mitigate the risk of swarms of drones or other attacks by Iran.

The U.S. has so far not provided any hard evidence Tehran was responsible for the attacks, but officials insist they have no doubt the cruise missiles and drones were launched from inside Iran.

Iran has denied involvement and warned the U.S. any attack will spark an "all-out war" with immediate retaliation from Tehran.

A military forensic team has been pouring over evidence from cruise missile and drone debris, but the Pentagon said the assessment is not finished. Officials are trying to determine whether they can get navigational information from the debris to provide hard evidence the strikes came from Iran.
