At least two paramilitary Hashd Shaabi members and many others injured after a massive explosion hit an arm deport that belonged to an Iranian- backed militia faction north of Baghdad on Tuesday.
The explosions took place in bases and warehouses belonging to militia groups under the umbrella of the mainly Iran-backed militias known as the Popular Mobilization Forces.
The explosion is the latest in a series of mysterious blasts at military bases and munitions depots around the country in the past few weeks.
In response to the explosions, Iraqi Prime Minister Adel Abdul-Mahdi banned unauthorized flights throughout the country and ordered all military camps and munitions warehouses to be moved outside Iraqi cities last week.
He ordered an urgent investigation into the explosions, whose results he said should be concluded within a week.
No one has claimed responsibility for explosions.
Last month, an explosion took place at a base in Amirli, in Iraq’s northern Salaheddin province that killed two Iranians and caused a huge fire. That attack was blamed on an unmanned drone that dropped explosives, with some Shiite militias blaming it on Daesh.
