Tributes have been paid to journalist Ed Moloney who has died aged 77.
Mr Moloney was known for his coverage of the Troubles in Northern Ireland and the activities of the Provisional IRA, writing for publications including Magill, the Irish Times and the Sunday Tribune.
Assistant General Secretary of the National Union of Journalists (NUJ), Séamus Dooley, said Mr Moloney was one of the most consequential journalists of his generation.
"He will be remembered for his courage, dogged determination and unyielding commitment to shining a light into the darkest corners of Northern Ireland's troubled history.
"During a crowded career he risked prison in defence of his sources and faced death threats for his investigative journalism," he said.
"He was fearless, courageous and outspoken and was never afraid of upsetting those who yielded power, influence and authority, either through elected office or membership of a proscribed organisation," he added.
On behalf of the NUJ, Mr Dooley extended sympathy to Mr Moloney's family.
Mr Moloney also wrote about the Troubles in books, 'A Secret History of the IRA', 'Paisley: From Demagogue to Democrat?' and 'Voices from the Grave: Two Men's War in Ireland'.
He was the director of Boston College's Belfast Project, known as the Boston tapes, which collected oral interviews with republican and loyalist militants who had been active during the Troubles.
Mr Moloney died in New York City on Friday, where he had been living and working.
He is survived by his wife Joan McKiernan and his son Ciarán Moloney.
