The U.S. plans to take "further actions" against Iran-supported organizations, according to the national security advisor.

• On Sunday, Jake Sullivan, the national security adviser, announced that the United States will take additional military measures against organizations supported by Iran.
• The president is determined to respond forcefully to attacks on U.S. troops, although he said he wouldn't discuss whether the U.S. has ruled in or out strikes in Iran.
• He stated that he does not seek a broader conflict in the Middle East.

On Sunday, Jake Sullivan, the national security adviser, announced that the U.S. will take additional military actions against Iran-backed groups, increasing tensions in the Middle East, even though Sullivan emphasized that the U.S. does not seek a broader conflict in the region.

The president has consistently stated that when American forces are attacked, we will respond, and we have done so multiple times in recent months, according to Sullivan during an interview on NBC News’ “Meet the Press.” Sullivan added that the recent U.S. strikes were not the end of the president's ongoing military response and that additional strikes and actions will be taken to send a clear message that the United States will respond when its forces are attacked or its people are killed.

Whether or not the U.S. will conduct strikes inside Iran remains unclear.

Sullivan stated that he wouldn't discuss the military action options that have been ruled in or ruled out from the perspective of the U.S. in response to Welker's inquiry about whether the U.S. has ruled out strikes inside Iran.

The president is resolved to retaliate strongly against attacks on our citizens and does not seek a broader conflict in the Middle East, he stated.

On Friday, the U.S. launched retaliatory strikes in Iraq and Syria against more than 85 targets linked to Iran's Revolutionary Guard and Iran-backed militants, in response to a Jan. 28 drone strike on an American base in northeastern Jordan that killed three U.S. troops and injured dozens of others. The base, known as Tower 22, is situated near the demilitarized zone on the border between Jordan and Syria, and is also close to the Iraqi border.

The Biden administration is attempting to prevent the spreading conflict in the region, which involves distinct but related challenges such as the attacks on Houthi targets in Yemen by the US and Britain. The Houthis, who have ties to Iran, have been firing at commercial ships and warships in the Red Sea, citing their actions as in solidarity with Palestinians amid the Israel-Hamas war.

The U.S. attacks in Iraq and Syria were condemned by Iran's foreign ministry on Saturday, with the ministry emphasizing that militants are acting independently. Iran has denied involvement in the Jordan drone strike.

If U.S. forces face another attack from Iranian-backed forces, there will be a response, according to Sullivan.

On Sunday morning, Sullivan was a guest on ABC's "This Week," CBS' "Face the Nation," and CNN's "State of the Union."
