Up to 50 people took part in a rally organised by the Irish Muslim Peace and Integration Council to protest over the actions of the so-called Islamic State.
The demonstrators gathered on Dublin’s O’Connell Street to distance Islam from the group, and show that it is a peaceful religion.
The “Not in Our Name” demonstration was organised in the wake of last month’s terrorist attack in Tunisia which killed 38 people, including three Irish citizens.
Organisers say it is believed to be the first protest of its kind held in Ireland.
