An airstrike in Iraq's eastern province of Diyala killed four members of the paramilitary Popular Mobilization Forces (PMF) and wounded two others on Sunday, according to security and paramilitary sources.

A PMF statement blamed the attack on "Israeli-American bombardment" targeting its 41st Brigade near the town of Miqdadiyah, some 90 km northeast of the capital Baghdad.

A provincial security source told Xinhua on condition of anonymity that two additional PMF members were wounded in the strike on a rural position.

The PMF held a funeral procession in Baghdad later on Sunday, with senior PMF leadership and citizens in attendance.

The strike comes amid sharply heightened tensions following a joint U.S.-Israeli attack on Iran on Saturday and subsequent retaliatory missile and drone launches by Tehran toward Israel and U.S. assets across the Middle East.
