In retaliation for the several rocket attacks against the U.S. Embassy and American bases in Iraq President Biden ordered the Pentagon to conduct a number of limited airstrikes against Iranian-led militias in Syria. 

Pentagon Press Secretary John Kirby said the following:

“At President Biden’s direction, U.S. military forces earlier this evening conducted airstrikes against infrastructure utilized by Iranian-backed militant groups in eastern Syria. These strikes were authorized in response to recent attacks against American and coalition personnel in Iraq and to ongoing threats to [that] personnel. Specifically, the strikes destroyed multiple facilities located at a border control point used by a number of Iranian-backed militant groups, including Kata’ib Hezbollah (KH) and Kata’ib Sayyid al-Shuhada (KSS).

This proportionate military response was conducted together with diplomatic measures, including consultation with coalition partners. The operation sends an unambiguous message: President Biden will act to protect American and Coalition personnel. At the same time, we have acted in a deliberate manner that aims to de-escalate the overall situation in both eastern Syria and Iraq.”
