Deputy Secretary of State Christopher Landau summoned Iraq’s ambassador to Washington Thursday to formally condemn Iranian-backed militia attacks on US diplomatic facilities and personnel in Iraq.

The readout acknowledged Iraqi security forces had responded to some attacks — then immediately noted that “some elements associated with the Iraqi government continue to actively provide political, financial, and operational cover for the militias.” Landau called the April 8 ambush of US personnel an “egregious terrorist attack.”

The State Department summoned Iraq’s ambassador this week to formally condemn attacks by Iranian-backed militias on US diplomatic facilities and personnel. Deputy Secretary Christopher Landau acknowledged Iraqi security forces made some effort to respond but delivered an unmistakable message: Baghdad’s failure to prevent these attacks — and the fact that elements within the Iraqi government are actively covering for the militias — is damaging the bilateral relationship.

The specific trigger was an April 8 ambush of US personnel. That’s not a protest outside a gate. That’s an armed attack on American forces, and it happened while a nominal ceasefire with Iran was supposed to be in effect.
