Here is the text of a statement by the G8 leaders, read by British prime minister Tony Blair, at Gleneagles.
“We condemn utterly these barbaric attacks. We send our profound condolences to the victims and their families.”
“All of our countries have suffered from the impact of terrorism. Those responsible have no respect for human life. We are united in our resolve to confront and defeat this terrorism that is not an attack on one nation but on all nations and on civilised people everywhere.
“We will not allow violence to change our societies or our values, nor will we allow it to stop the work of this summit. We will continue our deliberations in the interests of a better world. Here at this summit the world’s leaders are striving to combat world poverty and save and improve human life.
“The perpetrators of today’s attacks are intent on destroying human life. The terrorists will not succeed. Today’s bombings will not weaken in any way our resolve to uphold the most deeply held principles of our societies and to defeat those who would impose their fanaticism and extremism on all of us.
“We shall prevail and they shall not.”
