What to know about the US strikes in Iraq and Syria

BEIRUT >> The U.S. military has launched strikes on dozens of sites manned by Iran-backed fighters in western Iraq and eastern Syria in retaliation for a drone strike in Jordan in late January that killed three U.S. service members and wounded dozens.

Tensions had been rising since the Israel-Hamas war started on Oct. 7 and a week later Iranbacked fighters, who are loosely allied with Hamas, began carrying out drone and rocket attacks on bases housing U.S. troops in Iraq and Syria. A deadly strike on

the desert outpost known as Tower 22 in Jordan near the Syrian border further increased tensions.

The U.S. retaliation Friday had been expected since the Jan. 28 attack in Jordan.

Why is the area that was struck important?

The 85 targets struck in seven locations are in a strategic region where thousands of Iran-backed fighters are deployed to help expand Iran's influence from Tehran to the Mediterranean coast.

U.S. bases in Syria's eastern province of Deir elZour and the northeastern province of Hassakeh have come under attack for years. The Euphrates River cuts through Syria into Iraq, with U.S. troops and American-backed Kurdish-led fighters on the east bank and Iran-backed fighters and Syrian government forces to the west.

Bases for U.S. troops in Iraq have come under attack too.

Which targets were hit and how many people were killed?

The U.S. military said Friday that its massive barrage of strikes hit command and control headquarters; intelligence centers; rockets and missiles, drone and ammunition storage sites; and other facilities connected to the militias and the Iranian Revolutionary Guard's Quds Force, which handles Tehran's relationship with, and arming of, regional militias.

Syrian opposition activists said the strikes hit the Imam Ali base near the border Syrian town of Boukamal, the Ein Ali base in Quriya, just south of the strategic town of Mayadeen, and a radar center on a mountain near the provincial capital that is also called Deir el-Zour.

Rami Abdurrahman, who heads the Britainbased Syrian Observatory for Human Rights, said 29 rank-and-file fighters were killed in those strikes.

The attacks also hit a border crossing known as Humaydiya, where militia cross back and forth between Iraq and Syria, according to Omar Abu Layla, a Europebased activist who heads the Deir Ezzor 24 media outlet. He said the strikes also hit an area inside the town of Mayadeen known as “the security quarter.”

Iraqi government spokesperson Bassim al-Awadi said the border strikes killed 16 people and caused “significant damage” to homes and private properties.

The Popular Mobilization Force, a coalition of Iran-backed militia that is nominally under the control of the Iraqi military, said the strikes in western Iraq hit a logistical support post, a tanks battalion, an artillery post and a hospital. The PMF said 16 people were killed and 36 wounded, and that authorities were searching for other missing people.

How will Iran-backed fighters retaliate?

Iran and groups it backs in the region aim to put pressure on Washington to force Israel to end its crushing offensive in Gaza, but do not appear to want all-out war. The defeat of Hamas would be a major setback for Tehran, which considers itself and its allies the main defenders of the Palestinian cause.
