(CNN) Three rockets struck the US Embassy compound in Baghdad on Sunday, leaving one person injured, a US official told CNN initial reports indicate.

The official said the injury was minor and the individual had since returned to duty.

In a call with Iraqi Prime Minister Adil Abdul Mahdi on Monday, Secretary of State Mike Pompeo "expressed his outrage at the continued assaults by Iran's armed groups against US facilities in Iraq, including yesterday's rocket attacks against our Embassy, which resulted in one injury," a readout from State Department spokesperson Morgan Ortagus said.

"The Secretary underlined once again that these attacks demonstrate a wanton disregard for Iraqi sovereignty and a failure to rein in these dangerous armed groups. He appreciated Prime Minister Abd al-Mahdi's commitment to strengthen security to protect American personnel and diplomatic facilities," Ortagus wrote. "The Secretary noted that we view last night's attack on the Embassy as an attempt to distract Iraqi and international attention away from the brutal suppression of peaceful Iraqi protesters by Iran and its proxies."

Ortagus said that Pompeo expressed the US' "willingness to discuss the scope of our forces in Iraq over time."
