Senator Lindsey Graham, the chairman of Senate Judiciary Committee blamed Iran for the Saturday’s attack against two important Saudi oil facilities and called for military action against Iran’s oil refineries.

Graham tweeted: “Iran will not stop their misbehavior until the consequences become more real, like attacking their refineries, which will break the regime’s back.”

He added: “It is now time for the U.S. to put on the table an attack on Iranian oil refineries if they continue their provocations or increase nuclear enrichment.”

The drone attacks on Saudi facilities on Saturday reduced the oil production of the country by half and the world’s oil production by five percent.

Houthi militia an Islamic Republic of Iran’s proxy Shia militia group has accepted responsibility for the attacks on Saudi facilities, but the US Secretary of State Mike Pompeo has directly blamed Iran for this attack. 

Iranian officials have denied any role in these attacks. 

The attack on the two Aramco facilities in Saudi Arabia led to fires which were contained immediately.

The oil refinery in Buqayq province can produce seven million barrels per day. The facility was once before targeted unsuccessfully by Al-Qaeda in 2006.

Last month, Houthis of Yemen executed similar drone attacks against Saudi facilities, and in May, they targeted two other Saudi oil facilities.

Tensions have risen in the Persian Gulf after the attacks on several oil tankers near the Strait of Hormuz. American and several Arab countries blame Iran for these attacks. Iran's regime denies the allegations, however, the Islamic Republic officials in the past have repeatedly threatened to block the Strait of Hormuz if Iran cannot sell its oil due to sanctions.
