Saudi Arabia has declared five Iranian diplomats persona non grata, ordering them to leave the kingdom within 24 hours.
In a statement on Saturday, the Saudi foreign ministry said the affected officials include Iran’s military attaché, assistant military attaché and three other embassy staff.
The ministry said the decision followed the continued attacks by Iran on Saudi territory, warning that such actions could further strain bilateral relations.
Saudi Arabia said the attacks constitute “a flagrant violation of all relevant international conventions, the principles of good neighbourliness, and respect for state sovereignty”.
“They also violate the Beijing Agreement, UN Security Council Resolution No. 2817, and contradict Islamic brotherhood and the values and principles of the Islamic religion that the Iranian side constantly speaks of, confirming that these are merely words not reflected by actions,” the ministry added.
The kingdom said the situation could have “significant consequences” for present and future relations between the two countries.
Saudi authorities said the kingdom has come under missile and drone attacks since the outbreak of the conflict involving the United States and Israel against Iran.
The development makes Saudi Arabia the second country to expel Iranian officials since the conflict escalated, after Qatar took a similar action last week.
The conflict, which intensified following coordinated strikes on Iran in late February, has disrupted oil and gas exports across the region and heightened security concerns in Gulf countries hosting US military assets.
