Liberal senator Jim Molan has refused to accept the apology of a Greens MP who questioned his military record in Iraq, insisting his threat of defamation is still on the table.
Melbourne Greens MP Adam Bandt suggested in a TV interview on Wednesday the senator may have committed war crimes during the battle for Fallujah.
Senator Molan, a retired major-general who served as the chief of operations of the US-led coalition forces in Iraq, quickly threatened to pursue the Greens MP through the courts for defamation.
He invited Mr Bandt to "end the problem" and avoid legal action by making a public apology.
"I hereby apologise for those statements," Mr Bandt said in a statement on Thursday afternoon.
Senator Molan said he was deeply disappointed in the apology.
"Really there seemed to me to be no contrition that I think was proportional to the serious allegations that he made," Senator Molan told 2GB radio.
"I want him to reconsider it, and I consider that all my options are still on the table, so I'm not accepting it."
Home Affairs Minister Peter Dutton described Senator Molan as a "hero" who'd put his life on the line while people like Mr Bandt were "back home burning flags".
"He wouldn't have the guts or the capacity or the ability to serve his country like Jim Molan did," Mr Dutton told 2GB radio.
"Adam Bandt is a horrible individual. He demonstrates it on a daily basis in Parliament and frankly this just exemplifies it again in his pathetic comments about Jim Molan this week."
Senator Molan has attracted widespread criticism after re-posting anti-Islam videos by far-right group Britain First on his Facebook page last year.
