The message was conveyed as the United States warned it could respond to an Iranian government crackdown on protests, while Tehran has said it would strike US military and shipping assets in the event of a new attack.
“Saudi Arabia has informed Tehran directly that it will not be part of any military action taken against it, and that its territory and airspace will not be used for that purpose,” a source close to the Saudi military told AFP.
A second source close to the government confirmed that message had been communicated to Tehran.

The United States has repeatedly warned it could intervene against a deadly Iranian government crackdown on protests, while Tehran has said it would retaliate with strikes on US military and shipping targets.
