And the call has now gone out for more protests when he appears in central London on Wednesday this week.

Reports The Guardian: "Three men were arrested after they broke through a security barrier at around 10.45am today outside Eason's bookshop on O'Connell Street in Dublin, Ireland.

"The demonstrators, ranging from anti-war demonstrators to the Continuity IRA-aligned Republican Sinn Fein are now marching to a garda police station in the city centre demanding the release of the three arrested men.

"Gardai had earlier dragged a number of demonstrators off the street and during the fracas a male protester in a wheelchair was knocked to the ground.

"Protesters shouted 'Whose cops? Blair's cops!' as they taunted the gardai while Blair remained inside the bookshop. They also shouted: 'Hey hey Tony hey, how many kids have you killed today?'

One anti-war campaigner has attempted to make a citizen's arrest on former prime minister Tony Blair over alleged war crimes, reports the Press Association.

Activist Kate O'Sullivan managed to get through tight security to confront Mr Blair as he held a book signing in Dublin. "I went up to him and I said 'Mr Blair, I'm here to make a citizen's arrest for the war crimes that you've committed'," she said.

There are calls for protests in London on Wednesday September 8 when Blair is due at Waterstones Picadilly, 203-206 Picadilly, at 12 noon.

Says Counterfire website: "Join us to demonstrate against Tony Blair's book-signing and bring banners and something which will make a lot of noise!"
