The attacks mark the second time U.S. President Joe Biden has ordered retaliatory attacks against armed groups since he took office.
The United States said Sunday it carried out a round of airstrikes against Iranian-backed armed groups in Iraq and Syria, in response to drone strikes against U.S. personnel and facilities in Iraq.
In a statement, the U.S. military said it was targeting weapons operations and storage facilities at two locations in Syria and one in Iraq. It was not said if he believed anyone was dead or injured.
The attacks were led by President Joe Biden, the second time he has ordered retaliatory attacks against Iran-backed militias since taking office five months ago. Biden last ordered a limited bombing raid on a target in Syria on February, this time in response to rocket attacks in Iraq.
“As demonstrated by tonight’s strikes, President Biden has made it clear that he will act to protect U.S. personnel,” the Pentagon said in a statement.
The attacks occurred even when the Biden administration is potentially looking for them revive a 2015 nuclear deal with Iran. The attacks appeared to show Biden’s efforts to compartmentalize the attacks to protect American interests, while Tehran was involved in diplomacy.
Critics have said Iran cannot be trusted and have pointed to drone strikes as further evidence that Iran and its representatives will never accept the U.S. military presence in Iraq or Syria.
Biden and the White House declined to comment on the attacks Sunday.
Since the beginning of the year, there have been more than 40 attacks on US interests in Iraq, where 2,500 US troops are deployed as part of an international coalition to fight what is left of the ISIL group (ISIS ).
The vast majority have been bombs against logistics convoys, while 14 were rocket attacks, some of them claimed by pro-Iran factions seeking to pressure Washington to withdraw all its troops.
The attacks came a day after Iraqi Kurdish officials said three drones with explosives hit near the northern Iraqi city of Arbil, where the US has a consulate.
It also occurred when Hashed al-Shaabi, a pro-Iran paramilitary alliance opposed to the U.S. presence in Iraq, held a military parade near Baghdad attended by senior officials.
Two U.S. officials, speaking to Reuters on condition of anonymity, said Iran-backed militias had carried out at least five drone attacks on personnel facilities in Iraq. of the United States and the coalition since April.
The Pentagon said the target facilities were used by Iran-backed militias, including Kataib Hezbollah and Kataib Sayyid al-Shuhada.
One of the target facilities was used to launch and retrieve drones, a defense officer said.
The U.S. military used F-15 and F-16 fighter jets in the raids and said the pilots returned safely.
