Al-Harir Airbase, located near Erbil and housing US and international forces, was targeted in an armed drone attack, as reported by a security source on Saturday.
The assault caused damage to the airport infrastructure, but no human casualties have been reported at this time.
The Islamic Resistance in Iraq, a faction primarily composed of Iran-backed Shiite paramilitary groups, has claimed responsibility for a series of similar drone and rocket attacks since war broke out between Israel and Hamas. In a similar incident, the airbase caught fire late Thursday after being struck by two suicide drones, as confirmed by local authorities.
US and international forces stationed in Iraq and Syria have heightened their alert status following numerous attacks on their bases since the October 7 terror attack on Israel.
Iran's proxies resumed rocket and drone attacks on US bases in Syria and Iraq, breaking more than a year of relative calm.
Responding to the escalating situation, the US military on Thursday conducted strikes in eastern Syria, targeting a weapon storage facility used by Iran's Islamic Revolutionary Guard Corps (IRGC) and affiliated groups.
President Joe Biden emphasized that the strikes were a response to attacks on US troops. He also indicated the possibility of further responses if deemed necessary. However, numerous US threats so far have failed to deter the militant groups supported by Tehran.
Despite accusations, Iran has denied involvement in the attacks. Amir Saeid Iravani, Tehran's ambassador to the United Nations, claimed that separatist groups were reacting to the Israeli assault on Gaza, which has resulted in the death of over 10,800 Palestinians.
