A series of nationwide protests against the imminent attack on Iraq is being organised for Saturday.
Anti-war activists will be joined by representatives from the Labour Party, the Green Party, Sinn Fein, the Socialist Workers' Party, trade unionists, students, artists, poets and musicians in demonstrations from Derry to Cork.

People in Dublin are being urged to attend a rally at the Central Bank at 2 p.m. Protestors will then march to Government Buildings in Merrion Street.
In Belfast, the Irish Congress of Trade Unions is co-ordinating a demonstration beginning at 2 p.m. at the Art College on Donegall Street, before marching to he City Hall for a rally at 3 p.m.
In Derry, details are being finalised for a rally at the Guildhall beginning at 3 p.m.
Feeder marches are expected to join the main demonstration in both Northern cities.
Political and trade union representatives will also be in attendance in Waterford joining students in a rally beginning at 2 p.m in The Glen and marching to John Roberts (Red) Square.
A rally will begin at Penny's on O'Connell, Street, Limerick at 2 p.m., while a demonstration in Cork city is due to begin at 1 p.m. on Daunt Square.
The protests in the Republic are being co-ordinated by the Irish Anti-War Movement (IAWM), the Peace and Neutrality Alliance (PANA) and the Non-Governmental Organisation Peace Alliance.
On the day after the first attack on Iraq, anti-war groups are calling for workers to stop work for 10 minutes at 12 noon. A protest outside the US embassy in Dublin will also be called for 6 p.m.
Demonstrators' anger will be directed at US, British and Spanish governments for leading the attack on Iraq but the Irish Government will also come in for criticism, particularly if it continues to allow the US military use Irish airspace and Shannon landing facilities.
Mr Roger Cole of PANA said if the US is allowed use Irish facilities then the country will, for the first time, be involved in an "imperial war of conflict".
He also warned that Ireland could become a target of revenge attacks if we are seen to be assisting US efforts.
"If you involve yourself in a war then you must be ready to accept the consequences. You can't go around preparing to kill people without being prepared to die yourself," he told ireland.com.
