Baghdad: A new United States air strike targeted an Iraqi militia late on Taji road north of Baghdad on Saturday, Australian time, state TV said. It did not name the militia or provide further details.

The strike on the Iran-backed Popular Mobilisation Forces umbrella group near Camp Taji, an Australian military base, killed six people and critically wounded three, an Iraqi army source told Reuters.

But the umbrella group said it was meant for its fighters to hit a convoy of medics, not senior leaders as reported in some media.

"Initial sources confirm that the strike targeted a convoy of Popular Mobilisation Forces medics near Taji stadium in Baghdad," it said in a statement.
