Iran renewed bombing of sites in the Kurdistan region in northern Iraq, said an official from Komala Iranian-Kurdish opposition.
Atta Nasser said that the Iranian forces launched artillery fire and drone strikes on bases used by exiled Iranian group Komala in the Mount Halgurd area, near the Iranian border.
The strikes "destroyed some outposts, without causing casualties among our ranks," Nasser said.
On Thursday, the Iranian Revolutionary Guard Corps (IRGC) announced they would continue their attacks in Iraqi Kurdistan against the Iranian-Kurdish opposition.
For more than a week, Iran has launched sporadic strikes in northern Iraq, the most violent of which was on Wednesday, with more than 70 missiles and drone strikes in the autonomous region, targeting Iranian-Kurdish opposition groups.
At least 14 people, including a pregnant woman, were killed in the attacks, and 50 others were injured, mostly civilians.
The IRGC said in a statement that it launched a series of operations targeting terrorists in Iraq with "precision missiles" and "suicide drones."
The attacks come as unrest continues across Iran over the death of 22-year-old Mahsa Amini, a Kurdish woman.
Meanwhile, Iraqi President Barham Salih confirmed the Iranian bombing was a serious escalation and a violation of the country's sovereignty, security, stability, and safety of its citizens.
Salih met with National Security Advisor Qassim al-Araji to discuss the recent developments in politics and security-related matters in Iraq.
He also condemned the continued Turkish shelling of the Kurdish area, emphasizing that it is not sustainable or acceptable and has to be ceased immediately to prevent its ramifications.
The meeting reiterated the need to follow up on the security issues with high-level officials of neighboring countries, describing it as a "serious escalation."
They reiterated the need to promote dialogue and for Iraq and its neighbors to address the security challenges, noting that it should be based on shared security interests and in ways that would maintain Iraq's sovereignty and safeguard its citizens.
Earlier, Iraq summoned Iran's ambassador to hand over a worded note of protest to the Iranian government.
Iraq's note of protest said it "condemns this crime in continuous aggression by the Iranian forces against Iraq's sovereignty and territorial sanctity," the Foreign Ministry said.
The Foreign Ministry said the attack was a "dangerous development that threatens Iraq's security and sovereignty."
It is not yet clear whether Iraq will protest at the UN Security Council or will be satisfied with the position expressed by the protest letter.
However, linking the Iranian bombing with the continuation of Turkish shelling of Iraqi areas is a new Iraqi position in terms of dealing with both countries.
