Many world leaders are condemning the deadly attack on the U.S. consulate in Libya, but some in the Arab world are reserving their criticism for the film that appeared to provoke the violence.

British Foreign Secretary William Hague said there is no justification for the attack and called the killing of U.S. Ambassador Christopher Stevens “appalling.”

French President Francois Hollande said the attack is heinous and intolerable, while a German government spokesman said violence should never be used as a form of political debate.

Russia's Foreign Ministry said it considers attacks on diplomats terrorism.

But Egyptian Prime Minister Hisham Qandil made no direct mention of Ambassador Stevens while denouncing the film as an insult to the Prophet Muhammad.

Iran demanded an apology from President Barack Obama to Muslims. Afghan President Hamid Karzai called the release of the film a heinous act. He made no public comment about the ambassador's murder. But the White House says Mr. Karzai expressed his condolences for the loss of life in a telephone call with President Obama.

The Saudi-based Organization of Islamic Cooperation condemned both the killing of the ambassador and the film, while the Council on American-Islamic Relations in Washington called on Muslims to ignore the movie. It also condemned the attack on the consulate and on the U.S. embassy in Cairo.
