Several Iranian-backed Shia militias in Bahrain have joined the public chorus of various groups and political organizations denouncing the recent U.S. airstrikes in Iraq against Kata’ib Hezbollah (or the Hezbollah Brigades, KH).

Iranian military leaders have warned Washington against threatening military action after U.S. President Donald Trump said Tehran would be held responsible for anti-U.S. protests in Iraq.

The U.S. is prepared to take “preemptive” military action to prevent future attacks on U.S. forces, Defense Secretary Mark Esper said Thursday.
