Saudi Arabia, Qatar and Oman led efforts to talk US President Donald Trump out of an attack on Iran, fearing "grave blowbacks in the region", a senior Saudi official told AFP on Thursday, APA reports.
The Gulf trio "led a long, frantic, diplomatic last-minute effort to convince President Trump to give Iran a chance to show good intention", the official said on condition of anonymity, adding that dialogue was continuing.
Some personnel were moved out of a major US military base in Qatar on Wednesday, and staff at US missions in Saudi Arabia and Kuwait were warned to exercise caution as fears mounted of a US attack over Iran's crackdown on protesters.
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.
