The Iraqi government said Saturday that the U.S. airstrikes in western Iraq killed 16 people, including civilians, and injured 25 others.

Calling the airstrikes "blatant aggression," government spokesperson Basim al-Awadi told the official Iraqi News Agency that "the U.S. administration violated Iraq's sovereignty when its aircraft conducted airstrikes on the positions of our security forces in the Akashat and al-Qaim areas, as well as neighboring civilian places."

The Syrian Defense Ministry said in a statement that the U.S. air strikes on Saturday morning resulted in the loss of civilian and military lives, along with injuries and extensive damage to both public and private properties.

The targeted areas are where the Syrian army is actively combating remnants of the Islamic State terrorist organization, the ministry added.

The Syrian Observatory for Human Rights claimed that at least 23 members of an Iranian-backed militia had been killed in U.S. strikes in the country, Xinhua News Agency reported.

The U.S. hit Iran-linked targets in Iraq and Syria in retaliation for a deadly attack on a U.S. military base in Jordan on January 28, according to the White House.

The Iranian Foreign Ministry spokesperson Nasser Kanaani said in a statement that the attacks represented "another adventurous and strategic mistake by the United States that will result only in increased tension and instability."
