Saudi Arabia has threatened to attack Iran after it said trust with Tehran has been shattered following relentless attacks on the Gulf states.

Saudi foreign minister Prince Faisal bin Farhan accused Iran of premeditated hostile actions and said his country reserves the right to act militarily after Riyadh was targeted by Iranian ballistic missiles.

There are scant signs of de-escalation in the now three-week-old U.S-Israeli war on Iran. The conflict’s spread has caused unprecedented disruption to global energy supplies.

In the latest escalation, Iran accused Israel of striking its facilities in the huge South Pars gas field on Wednesday.

It retaliated by firing missiles at Qatar and Saudi Arabia as it vowed attacks on oil and gas targets throughout the Gulf, sending already elevated oil prices shooting higher.

Iran’s foreign ministry spokesperson said on Thursday that bin Farhan’s remarks were ‘unfair’ and one-sided.
