Three rockets hit the U.S. Embassy compound in Baghdad on Sunday, injuring one person, a U.S. official told CNN.
According to a State Department spokesperson, local authorities "are aware of reports of rockets landing in the International [Green] Zone," the area in which the embassies of the United States and several other countries are situated.
Numerous attacks have been reported within the Green Zone over the past several months as tensions continue to rise between the U.S. and Iran following the U.S. killing of Qassem Soleimani and Iran's retaliation strike on an Iraqi base containing U.S. troops.
Although the State Department did not say Tehran was responsible for the recent rocket strike, security remains on high alert.
"The security situation remains tense and Iranian-backed armed groups remain a threat. So, we remain vigilant," a spokesperson said.
No group has claimed responsibility for the attack.
