Tributes have been paid to the veteran journalist and commentator Robert Fisk who has died at the age of 74.

Robert Fisk worked as Northern Ireland correspondent for the Times of London in the early 1970s and later became the Middle Eastern correspondent for that paper, moving to the Independent in 1989.

He lived in Beirut from 1976 and his book on the Lebanese conflict, 'Pity the Nation', was published in 1990.

He also reported on conflicts including the Soviet-Afghan war, the Iran-Iraq war, the Gulf war, the war in Bosnia and the ongoing Syrian war.

Robert Fisk’s relationship with Ireland began in the 1970s - he later completed a PhD at Trinity college and had a home in Dalkey in Co Dublin. In recent years, he took Irish citizenship.

The Irish Times reported he suffered a stroke at his Dublin home on Friday and died later in hospital.

President Michael D Higgins said that the world of journalism and informed commentary on the Middle East had lost one of its finest commentators.

President Higgins said generations had relied on Robert Fisk for a critical and informed view of what was taking place in conflict zones of the world, and he said his Irish citizenship had meant a great deal to him.

Taoiseach Micheál Martin said Fisk was "fearless in his reporting, with a deeply researched understanding of the complexities of Middle Eastern history and politics".

Robert Fisk's books included 'Pity the Nation: Lebanon at War', 'In Time of War: Ireland, Ulster and the Price of Neutrality' and 'The Great War for Civilisation: The Conquest of the Middle East'.
