At least one U.S. military service member in Syria suffered a minor injury and up to three suspected Iran-backed militants were killed on Wednesday, the U.S. military said, in the second consecutive day of violence.
The latest exchange of fire underscored soaring military tensions even amid diplomatic efforts between Tehran and the West to try to save Iran's 2015 nuclear deal with major powers.
It came a day after President Joe Biden authorized U.S. air strikes in Syria on an ammunition depot and other facilities used by groups affiliated with Iran's elite Revolutionary Guards Corps (IRGC).
