Critics took aim at President Biden's Middle East policy after three Americans service members were killed in an attack on a base in Jordan near the border with Syria. "Hit Iran now," Sen. Lindsey Graham, R-S.C., said in a statement after the Sunday attack. Graham's comment comes after three U.S. service members were killed and 25 more were injured in a drone attack on northeast Jordan that sits close to the border with Syria, U.S. Central Command (CENTCOM) confirmed. "On Jan. 28, three U.S. service members were killed and 25 injured from a one-way attack UAS that impacted at a base in northeast Jordan, near the Syria border. As a matter of respect for the families and in accordance with DoD policy, the identities of the servicemembers will be withheld until 24 hours after their next of kin have been notified," CENTCOM said in a statement. "Updates will be provided as they become available."

Three US service members have been killed and "many" others wounded during an unmanned aerial drone attack on US forces stationed in northeastern Jordan near the Syrian border, President Joe Biden has said, blaming Iran-backed groups for the attack. The United States military said in a statement that at least 25 people were injured. "While we are still gathering the facts of this attack, we know it was carried out by radical Iran-backed militant groups operating in Syria and Iraq," Biden said in a statement on Sunday. Biden said the US "will hold all those responsible to account at a time and in a manner [of] our choosing." Jordanian state television quoted Muhannad Mubaidin, a spokesperson for Jordan's government, as saying the attack happened outside of the kingdom across the border in Syria. There was no immediate comment from Iran.

Pro-Iranian forces in Syria have said they have a "long arm" to respond to further United States air strikes on their positions, after tit-for-tat missile and drone attacks in Syria over the last 24 hours. The online statement, released late on Friday and signed by the Iranian Advisory Committee in Syria, said US air strikes had left several of their fighters dead and wounded, without specifying the fighters' nationality. "We have the capability to respond if our centres and forces in Syria are targeted," the statement said. On Friday night, two Syrian opposition activist groups reported a new wave of US air attacks on eastern Syria, which hit positions of Iran-backed militias, after rockets were fired at bases in Syria housing US troops. Several US officials, however, denied that attacks were launched late on Friday.
