Karzai said he hopes the world believes that his country is "not the place of terrorism" after the announcement that the al Qaeda leader was killed in neighboring Pakistan.
"If the international troops/forces are true allies of the Afghans -- they should come out and say that the killing of Afghans, children and elders which took place over the many years on a daily basis was not a good idea," Karzai said on RTA TV.

German Chancellor Angela Merkel
"With the commando action against Osama bin Laden and his killing, the U.S. military has achieved a decisive strike against al Qaeda," she said.
"At his command and in his name, terror was enforced into many countries against men women and children, Christians as well as Muslims. Osama bin Laden suggested that he was operating in the name of Islam, but in reality he makes a mockery of the fundamental values of his own and every other religion."

Former Lebanese Prime Minister Saad Hariri
"The harm that Osama Bin Laden has inflicted to the image of Islam and the Arab causes is no less than the harm caused by enemies to the causes of Muslims and Arabs everywhere. ... Our national and Muslim history will not forgive this man. He has been, for two consecutive decades, a black mark in this history, and voluntarily poisoned the minds of thousands of youth with the culture of terrorism and killing and sabotage and destruction, and has placed Islam, which is a religion of justice and forgiveness and dialogue and good deeds, in a hostile position towards other civilizations, religions and cultures."
Muslim Council of Britian:
"Few will mourn the reported death of Osama bin Laden, least of all Muslims.
