"This resulted in the death of seven of our heroic fighters and the injury of 13 others," the ministry said of the strike in Anbar province, saying it specifically targeted the base's military healthcare clinic. Rescue operations were ongoing, it added.
The base hosts Iraqi police, soldiers from the regular army and Hashed al-Shaabi forces, a security official told AFP.
It was hit by a deadly strike on Tuesday that Hashed al-Shaabi forces, also known as the Popular Mobilisation Force (PMF), blamed on the United States.
Tuesday's strike was the deadliest in Iraq since the start of the US-Israeli war on Iran on February 28, killing 15 fighters, including a commander.
The former paramilitary coalition is now part of Iraq's regular armed forces, but also includes brigades belonging to Iran-backed groups.
The attack prompted the government late on Tuesday to grant the PMF a "right to respond" to any attack against them.
Throughout Tuesday evening and into Wednesday morning, the sounds of military aircraft flying over the capital Baghdad were particularly loud, AFP journalists reported.
Since the war began, pro-Iran armed groups have claimed responsibility for attacks on US interests in Iraq and across the region, while strikes have also targeted these groups, including on state-linked positions.
The Pentagon has acknowledged that combat helicopters carried out strikes against pro-Iran armed groups in Iraq during the current conflict.
Baghdad has condemned attacks targeting foreign soldiers and diplomatic missions, as well as strikes against PMF positions.
