first, from egypt, a report from margaret warner. >> warner: cairo's khan al khalili market has stood for 630 years. shoppers and sellers jam the streets and alleys. and here, 5,000 miles away from america's shores, the 9/11 attacks still resonate a decade later. >> ( translated ): no one supports this! we were shocked beyond belief. >> warner: but there was another sentiment, as well. >> ( translated ): i felt that the american government deserved it-- not the people, but the government deserved it. >> warner: there was little debate, however, on one point-- like 75% of egyptians in a recent poll, no one here believed that arabs or muslims, much less egyptians, could possibly have been involved. >> ( translated ): most egyptians are muslims, and islam does not permit such violence. >> warner: some hinted at more powerful forces at work. >> i don't think it was only al qaeda that was doing this. >> ( translated ): muslims don't do that! this is an economic conspiracy at its highest level. >> warner: the 19 hijackers were all arabs, of course. their ringleader, mohammed atta, grew up i

, the authorities' clear message is that they will not tolerate a return to unrest. >> brown: margaret warner has second part of our arab spring update. >> warner: now to the key power on the penninsula-- saudi arabia, which in word and deed has expressed its misgivings about popular dissent in the region. at the same time, the kingdom is looking for ways to let some steam out of the political pressure cooker. today it held elections for seats to some 300 municipal councils. but only men were allowed to vote, and turnout was low. to explore all this, we turn to caryle murphy, a pulitzer prize winning former correspondent for the "washington post." she is now a fellow at the wilson international center for scholars and has just returned from three years in saudi arabia for "global post." and nice to see you again, caryle. >> nice to be here. >> warner: so fair to say that saudi arabia is still doing whatever it can to prevent infection from the arab spring, whether it's to its own neighbors, like bahrain, or at home. >> absolutely. i mean, it was very rattled by all these events earlier in the

margaret warner has that story. three bloody recent attacks in afghanistan claimed many lives, but the greatest casualty may be the u.s. alliance with pakistan. in ge june insurgents laid siege to kabul's inter-continental hotel killing 11. ea truck ,s ruck bomb wounded 77 u.s. troops in eastern afghanistan. days later back in kabul, insurgents fired grenades and automatic weapons at the u.s. embassy and nato compound. 16 died in the 20-hour assault. against this back drop last week admiral mike mullen chairman of the joint chiefs of staff went to capitol hill and dropped a bombshell. >> the network for one acts as a veritable arm of pakistan's internal services intelligence agency. with i.s.i.support, they conducted and planned that truck bomb attack as well as the assault on our embassy. in choosing to use violent extremism as an instrument of policy, the government of pakistan and most especially the pakistani army and i.s.i. jeopardizes not only the prospect of our strategic partnership but pakistan's opportunit
