Barack Obama and John McCain, rivals in the White House race, have said they will appear together on the anniversary of the 11 September 2001 attacks, adding that they would take part in the commemorations in New York, where two of the attacks took place.
The senators said that in order to honour the memory of the nearly 3 000 people who died, they would put aside politics.
On that day, hijacked planes were crashed into New York’s Twin Towers, the Pentagon in Washington and a field in Pennsylvania.
“All of us came together on 9/11 – not as Democrats or Republicans – but as Americans”, the joint statement said.
“In smoke-filled corridors and on the steps of the Capitol ; at blood banks and at vigils – we were united as one American family.
“On Thursday, we will put aside politics and come together to renew that unity, to honour the memory of each and every American who died, and to grieve with the families and friends who lost loved ones.”
The event will take place at Ground Zero, where the Twin Towers of the World Trade Center collapsed. It will be the first time Mr McCain and Mr Obama will be together since they were formally nominated as presidential candidates at their parties’ just-completed national conventions.
As the parties nominations are over, both candidates have been gearing up for the last weeks of campaigning up to the 4 November election. But the two senators agreed not to run television ads critical of each other on Thursday. John McCain’s campaign team even said they would not run any ads.
