On Thursday, a US contractor was killed and five US service members and one US contractor were wounded in an attack on a coalition base in northeast Syria. In response, President Joe Biden authorized a precision airstrike against facilities used by groups affiliated with Iran’s Islamic Revolutionary Guards Corps (IRGC). The US Central Command forces conducted the airstrike in eastern Syria, targeting facilities used by the IRGC, and the US is closely monitoring the situation and will take appropriate action to protect US personnel and interests in the region.
