Two overnight rocket attacks were directed against American diplomatic and military facilities, Iraqi security forces said on Sunday, just over a week since unprecedented arrests prevented a similar attack.
Since October, US diplomats and troops across Iraq have been attacked by around three dozen missile attacks that Washington has accused of pro-Iranian armed groups.
As a first step of this kind, Iraqi elite troops arrested more than a dozen Tehran-backed fighters in late June who were allegedly planning a new attack on the Baghdad Green Zone, which is home to the United States and other foreign embassies.
Iraqi government officials said the raid would serve as a "message" to ward off future attacks, but the militants made another attempt early Sunday.
A rocket that was fired at the Green Zone landed near a house and wounded a child, according to the Iraqi military.
"At the same time, our forces prevented another attack and seized a Katyusha missile and launcher aimed at the Taji base north of Baghdad," where US-led coalition forces are stationed.
The trials occurred just a few hours after the U.S. embassy tested a new missile defense system called C-RAM, according to a senior Iraqi security source.
The C-RAM, which was set up at the embassy earlier this year, searches for incoming projectiles and explodes them in the air by targeting them at several thousand bullets per minute.
There was no immediate comment from the embassy on whether the system was used against the missile overnight.
