"Prominent Rudaw war reporter and journalist Shifa Gardi has been killed in Mosul as she covered clashes," Rudaw said on social media.
"Journalism remains male-dominated -- Shifa Gardi broke those perceptions and stereotypes -- we pay tribute to her courageous journalism," the channel said.
Rudaw editors told AFP she was killed by an explosive device on a road in west Mosul and said that the cameraman accompanying her was wounded.
He was transferred to Arbil, the nearby capital of Iraq's autonomous Kurdish region where the channel is headquartered.
