Recently there have been four attacks on weapons storage facilities belonging to Iraq’s Popular Mobilization Units (PMU) militia. Some factions of the PMU are believed to be Iran proxies, which might explain why there have been accusations of possible US and Israeli involvement. The latest attack took place even though prime minister Mahdi had closed Iraqi airspace to all unauthorised flights of drones, spy planes, jets and helicopters; including the US-led coalition. With Israel being suspected of organising these attacks, some claim that the United States and Russia have allowed them to do so. Iraq’s president said his country does not want to become a battleground for other countries at the expense of its people. ‘Iraq's interest comes first, and the nation will not allow others to turn it into a land for competition.’
