(CNN) -- What role did Pakistan play in the operation against Osama bin Laden? I would be surprised if Pakistan played a significant role in the operation to apprehend and kill Osama bin Laden, based on the fact that the drone strikes that the U.S. conduct in the tribal areas are done covertly, the authorities in Pakistan are not informed until the very last minute, because of the fear of information leaks. An operation of this scale in the central urban heartland of Pakistan would mean that information would be kept on a need-to-know basis. Only a few people within the CIA would have known about this operation, it would definitely not have gone out to another country's intelligence agency, especially when there's so little trust with the ISI [Inter-Services Intelligence, the Pakistani intelligence service].Gohel: Pakistani authorities will have been kept in the dark because of a lack of trustProtests and propaganda set to follow the death of Osama bin Laden, he saysGohel: Retaliation attacks are likely, but may not happen immediately. 
 Question:U.S. interests, U.S. personnel, _ embassies and consulates will have to take extra precautions.

(CNN) Al Qaeda in the Islamic Maghreb, often seen as a fractured and undisciplined group, apparently has carried out its second major terror attack in two months -- claiming more than 20 lives in the assault on a luxury hotel and two other targets in Ouagadougou, the capital of Burkina Faso. The gun attack on the Splendid Hotel bears many similarities to that on the Radisson Blu hotel in Bamako, Mali, on November 20 in which 22 people were killed. Both targets were popular with Westerners and international (especially U.N). officials; they were "soft," rather than military installations or police stations. The attackers (two in Bamako, possibly four in Ouagadougou) were armed with automatic weapons, their aim to kill and then take as many hostages as possible.Al Qaeda in the Islamic Maghreb appears to have been rejuvenatedIts affiliates are based in areas with limited state security 
 Question:Belmoktar is leader of Al Mourabitoun, which carried out another deadly hotel attack in the Malian town of Sevare last August in addition to the _ and Ouagadougou attacks.

(CNN) -- Asiana Airlines Flight 214 was seconds away from landing when the passengers sensed something horribly amiss. The plane was approaching San Francisco International Airport under a beautifully clear sky, but it was flying low. Dangerously low. Benjamin Levy looked out the window from seat 30K and said he could see the water of the San Francisco Bay about 10 feet below. Even for an airport where landing strips run close to the water, the descent seemed alarming to the San Francisco man. "I don't see any runway, I just see water," Levy recalled. Further back in the Boeing 777, Xu Das had the same realization.Flight recorders have been found, the NTSB saysAsiana identifies the two 16-year-old girls killed in the crash182 people were hospitalized, while 123 were uninjuredPassengers say the plane's rear struck the edge of the runway
