Officials have prepared a range of options for the president to consider.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Despite a memorandum of understanding signed by both countries in June aimed at ending the war, talks broke down and the U.S. and Iran renewed strikes, with the strategic Strait of Hormuz as the primary flashpoint.
Across the region, fighting in Yemen between the Iranian-backed Houthis and Saudi-backed Yemeni forces has intensified in recent weeks and the militia group has also launched strikes on Saudi Arabia.
Saudi-led coalition spokesperson, Major General Turki Al-Maliki said Houthi attack against Saudi Arabia are regional security threats to peace and said they must stop all their attacks.
King Khalid Airport was attacked 20 times since Oct. 1, according to Al-Maliki. At least 17 people were killed and 333 were injured between Oct. 7 to Oct. 11, according to Al-Maliki.
At least two people were killed and others were injured after ballistic missiles struck the Yemeni presidential palace in Aden, the seat of Yemen's internationally recognized government, according to the minister of information and a government spokesperson.
Prime Minister Shaya al-Zindani and government ministers were unharmed after four ballistic missiles hit the palace, according to the minister and spokesperson.
The Houthis responded saying any Saudi military presence is a legitimate target.
"The bombing of the Saudi enemy's military operations headquarters in Aden comes within the context of the declared equation of striking Saudi mobilizations wherever they are, and considering any Saudi enemy military presence a legitimate target for our forces wherever they are," Yahya Saree, a spokesperson for the Yemeni Armed Forces, said Thursday.
The United Kingdom Maritime Trade Operations said it has recorded 20 reported attacks in the Strait of Hormuz since Oct. 1, with two incidents reported on Wednesday.
In each case, vessels were struck by what the UKMTO described as "unknown projectiles."

A U.S. official said Iran lied about a cargo ship that sunk on Wednesday and that Iran attacked the ship, likely with a missile.
Iran claimed the cargo ship sunk after striking a naval mine as it was attempting to navigate the Strait of Hormuz.
