Two rockets have struck a training base south of Baghdad where US-led coalition troops and NATO trainers are present, Iraq's military has said, EDNews reports citing Aljazeera.
The attack, the third targeting military bases hosting foreign forces in a week, targeted the Besmaya base south of Baghdad on Monday night, read the statement, making no mention of casualties.
Spanish forces linked to the US-led coalition fighting the Islamic State of Iraq and the Levant (ISIL or ISIS), as well as NATO training forces, are present in Besmaya.
Earlier on Monday, US Secretary of State Mike Pompeo warned Iraq that the US would retaliate "as necessary" against any new assaults on Americans.
Since late October, there have been 24 rocket attacks on the US embassy in Baghdad or bases where foreign troops are deployed, killing three American military personnel, one British soldier and one Iraqi soldier.
No attacks have been claimed but Washington has blamed Kataeb Hezbollah, a hardline faction in the Hashd al-Shaabi (Popular Mobilisation Forces) state-sponsored military network.
