The news of the suicide bomb attack was received here by some of the soldiers listening to shortwave radio. Word has gotten out. Also, the commanders of this Army unit that I'm with are telling the troops who are up toward the front lines, more toward where the civilians would be in Baghdad, to be on their guard and not let anyone approach them; to keep them at arm's length.

The U.S. military has been coming into contact with Iraqi civilians from the moment those troops rolled into Baghdad. Presumably, there is going to be the need at some point to restore order and come into further contact, close contact with Iraqi civilians. There lies the rub: that you really don't know who is going to be a suicide bomber or not. It's the kind of quandary the military finds itself in.

One Marine said that a man approached a checkpoint and pulled the pin on one or several grenades, which then detonated. At least four Marines are said to be seriously injured, and one person is dead, believed to be the suicide bomber. This is just the kind of thing that U.S. military officials had worried about — the Iraqis resorting to unconventional means, carrying out attacks against American troops.

I've been out in the streets today, talking to many Iraqis. The initial impression is, of course, they are very happy. The things they are telling me now are nothing that I would have heard two or three days ago. They said that they are tasting freedom for the first time. They can trust people now and they feel that they can speak. They also said that they are very nervous and don't like all the looting that is going on. The want the U.S. Marines that are in the city to do more to protect them.
