The Solidarity to Organise Peace (STOP) Campaign has called for a two-minute silence to be observed at 11 a.m. tomorrow, in Northern Ireland and the Republic.
A spokesman for the campaign, Mr Paul Burton, said he was calling on people to stand in silence in support of three aims: in rememberance of all the people who have died in over 25 years of violence in the North, in support of the talks process and in total opposition to violence.
The initiative has received cross-party support as well as from the Irish Business and Employers' Confederation, the Irish Congress of Trade Unions and the National Parents' Council.
Mr Burton said members of the Dail and Seanad would be observing the two-minute silence. "All city and provincial buses will stop, all taxi men in the Republic will stop, banks, post offices and supermarkets will stop, all Government offices and schools, colleges and universities will stop," he said.
