On 4 December, Ain Assad airbase in Anbar province was hit by several rockets. Two days later on 6 December, in a similar incident, Balad airbase in north of Baghdad was hit by Katyusha rockets. None of the attacks have casualties.
USA officials as usual accused Iran and Iraqi groups close to Iran.
An official of US Department of State said maybe Iran is behind the attacks and we wait for more information.
This proclaim is stated while the security of Iraq airspace and airbases is completely controlled by US and by expressing these fake accusations, US has repeatedly tried to hide the truth and make propaganda campaign against Iran.
