Shafaq News/ The Syrian Observatory for Human Rights reported on Monday that "Iranian militias" targeted a US military base in Syria.

"the bombing caused material losses”

"The Iranian militias in western Euphrates region targeted the American base from its positions in the countryside of Deir ez-Zor." The observatory quoted sources as saying.

In this context, the reconnaissance aircrafts of the US forces and the Global Coalition flew over the region, according to the observatory.

Earlier, The United States said on Sunday it carried out another round of air strikes against Iran-backed factions in Iraq and Syria, “this time in response to drone attacks by the factions against U.S. personnel and facilities in Iraq.”

In a statement, the U.S. military said it targeted operational and weapons storage facilities at two locations in Syria and one location in Iraq. It did not disclose whether it believed anyone was killed or injured but officials said assessments were ongoing.

Iraqi groups aligned with Iran in a statement named four members of the Kata’ib Sayyed al-Shuhada faction they said were killed in the attack on the Syria-Iraq border. They vowed to retaliate.

The strikes came at the direction of President Joe Biden, the second time he has ordered retaliatory strikes against Iran-backed factions since taking office five months ago. Biden last ordered limited strikes in Syria in February, that time in response to rocket attacks in Iraq.

"As demonstrated by this evening's strikes, President Biden has been clear that he will act to protect U.S. personnel," the Pentagon said in a statement.

A source told Shafaq News Agency that four members of the Popular Mobilization Forces were killed and others injures in the airstrikes people were killed in an American bombing on the Iraqi border with Syria.
