"Several rockets fell on the territory of the Taji base hosting US military," a security source told Sputnik.
According to Iraqi security media, one rocket struck an Iraqi army helicopter used to fight Daesh, while another landed on an artillery warehouse and caused damage. The third rocket landed on the second squadron of the Iraqi Air Force but did not explode.
Missiles frequently target the Green Zone, the 2.9-square-mile area in the Karkh district of central Baghdad where government buildings and embassies are located.
The Joint Operations Command of the Iraqi Armed Forces in mid-June announced that Iraqi Prime Minister Mustafa al-Kadhimi had ordered the establishment of a special committee to stop such strikes from occurring.
Iraqi security forces are currently investigating the incident.
The Iraqi military on Friday said that four Katyusha rockets hit the Besmaya military base south of Baghdad, which is used by US-led coalition troops. The incident caused some material damage but no casualties.
