Top Al Qaeda official arrested in Cairo, Egyptian authorities say CAIRO - A leading member of the extremist group al-Qaeda has been arrested in Cairo International Airport, where he was traveling on an Emirates Airline flight, according to airport officials. Egyptian-born Mohammed Ibrahim Makkawi, known as Saif al-Adel (the "sword of justice" in Arabic) had traveled to Egypt from Pakistan, via Dubai, the officials said. (FBI) - Saif al-Adel is thought to be affiliated with the Egyptian Islamic Jihad and is believed to be a high-ranking member of the al-Qaeda organization. Makkawi is on the FBI's most-wanted list for the bombings of the U.S. embassies in Dar es Salaam, Tanzania and Nairobi, Kenya in 1998. The FBI has offered a $5 million reward for his arrest. Makkawi was briefly Osama Bin Laden's security chief, overseeing its military operations and a senior member of the extremist organization. A former Egyptian military officer, he was considered a chief rival of Ayman al-Zawahiri, who took the helm of al-Qaeda after Osama bin Laden was killed by U.S. Navy SEALs in a raid in 2011.
