Eight members of an Iranian Kurdish opposition group were killed on Friday when Iranian drones and rockets struck their camp in Iraq’s autonomous Kurdistan region, according to the group.

Idriss Kohlwazi, an official from the Komala party, told Agence France-Presse that Iranian forces attacked a camp belonging to the group and its surrounding area near Sulaymaniyah early Friday.

The strikes killed eight Komala members and wounded several others, Kohlwazi said. The party blamed Iran for the attack, while Tehran had not immediately issued a public statement about the operation. AFP report

Komala is an Iranian Kurdish opposition organization operating in exile from Iraq’s Kurdistan region. Iran has repeatedly targeted the group and other Iranian Kurdish parties, accusing them of conducting armed activities against the Islamic Republic.

Friday’s attack marked the most significant escalation against Iranian Kurdish opposition groups in Iraq since a fragile ceasefire was reached in April. Iran continued carrying out limited attacks against their positions even after the truce began.

The strike came amid renewed fighting between Iran and the United States, the most serious escalation between the two countries since the April ceasefire.

In a separate incident, coalition forces intercepted and destroyed eight explosive-laden drones over Erbil between 4:19 a.m. and 5:25 a.m. on Friday, according to the Kurdistan region’s counterterrorism authorities.

No casualties or material damage were reported, and authorities did not identify where the drones were launched from or their intended targets. Kurdish counterterrorism statement reported by Peregraf

Erbil hosts a major U.S. diplomatic complex, while military advisers from the international coalition are stationed at Erbil International Airport.

No group immediately claimed responsibility for the drones launched toward Erbil.
