CAIRO, FEB. 13 -- The deaths of Iraqi civilians in a U.S. bombing raid today produced sharp criticism from some Arab officials and new worries that the Arab members of the U.S.-led coalition may face growing public pressure to stop the war.

"There is a changing mood even among the so-called moderate Arab states that this war is far more messy and destructive than we asked for," said Walid Khazziha, an economist at the American University in Cairo. "This kind of terrible event will widen the rift between some of these states and their own people."

Arab states reacted in different ways to the incident. Algeria and Tunisia -- which, while officially neutral, have been expressing increasing support for Iraq -- were quick to condemn the attack.

"The savage bombing of civilians is contrary to human values and international conventions," said the Tunisian Foreign Ministry in a statement. President Zine Abidine Ben Ali declared Thursday an official day of mourning for Iraqi civilian casualties, according to Reuters.

In neighboring Algeria, the official APS news agency described the bombing as "one of dozens of massacres that have been aimed at our Arab nation."

Jordanian riot police prevented more than 150 people from marching on the U.S. Embassy tonight in Amman to protest the air raid. "People are really sad{dened} by what happened in the shelter," a senior security official told Reuters. "They were even more moved when they saw the television pictures of the charred bodies."

Egypt, which has been a key Arab member of the allied coalition against Iraq, maintained public silence on the attack. But a senior Egyptian official said privately that the deaths would have no impact on Egyptian support for the war.

"One feels very sorry for the loss of life in Iraq," said Osama El Baz, a senior adviser to President Hosni Mubarak, in an interview before the deaths were reported. "But we still believe the battle has started because of Iraqi intransigence. We see the only way out of the devastation is an Iraqi agreement to withdraw from Kuwait and implement the U.N. resolutions."

But Egyptian opposition figures, who so far have been deeply divided over the conflict, were quick to condemn the raid. "It is a very sad time for us, a catastrophe," said Mohammed Maamoun Hodaiby, a leader of the outlawed but officially tolerated Moslem Brotherhood.

"We don't believe in Saddam Hussein -- he has killed many of our brothers. But that does not mean we don't care about the 18 million people of Iraq. They are a big part of the Arab Moslem world. If they are destroyed, it means a big part of us is destroyed. If their power and wealth are gone, it means a big part of our power and wealth are gone as well."
