so mahmoud abbas is in an interesting, difficult position. he's a leader of the palestinians but has no voice in this critical moment. on the other hand, he's still for nonviolence. there's talk he'll go to the egyptian leadership about a way to end the fighting. it isn't clear whether he has influence at all on the palestinians in gaza. it's a major challenge to mahmoud abbas, who is strongly against violence and has termed the not only hamas and israel as makers of war. so he's actually gone out on a limb criticizing hamas at this difficult time for the palestinian people. >> indeed. all right. well, thank you very much. appreciate your reporting, martin fletcher. appreciate it. and coming up, thousands of people in detroit have had their water cut off because they didn't pay the bill. i'll talk to two people working hard to get the water turned back on.
