The deadly US attack on a mosque in Fallujah, Iraq, today will reverberate around the Arab and Muslim world.
That's the view of Ibrahim Hooper of the Washington-based Council on American-Islamic Relations, who says the attack will damage America's interests and its image.
Hooper says when you have American missiles killing dozens of people praying in a mosque, it's not going to help the campaign "to win the hearts and minds of the Iraqi people."
Hooper says today's attack, and last week's mutilation of the bodies of US civilian security personnel, are both violations of international agreements of the rules of war, and in each case, those responsible must be held accountable.
Military officials say the attack on the mosque was ordered because insurgents were firing from inside. But Hooper says he'll reserve comment on that until the facts are in.
