U.S. launches air strikes in response to Iran-linked drone attack in Syria.

An American contractor was killed and six others were wounded in a drone attack on a coalition military base in Syria, prompting the US to launch retaliatory airstrikes on facilities used by groups affiliated with Iran's Islamic Revolutionary Guard Corps. The airstrikes killed eight pro-Iranian fighters. The US maintains a presence in Syria to apply pressure to the remnants of the Islamic State militant group and to try to limit Iran's influence in Syria. The US Congress is currently considering repealing bills that allowed for the use of force against Iraq's government during the Iraq War and the 2001 AUMF that has been stretched to allow the US to target militant groups in Syria, Pakistan, the Philippines, and beyond.
