Abdulaziz Muhammad Saleh bin Otash

Bin Attash was killed by Ethiopian forces in Somalia in December 2011.

On February 3, 2006, 23 people, 12 of them al-Qaeda members, escaped from a Yemeni jail, according to a BBC report. They reportedly escaped by digging a tunnel.

The FBI added several new names to the "wanted" lists, in response to the Yemen escape of 2006. However, none of the 17 Yemen plot suspects from the 2002 terror alert appeared again among the new FBI names.

In early 2002, according to an FBI report, as a result of US military operations in Afghanistan and of on-going interviews of detainees in Guantanamo Bay, Cuba, information became available on February 11, 2002 regarding threats to US interests which indicated that a planned attack may have been about to occur in the United States or against US interests in the country of Yemen on or around the next day, February 12, 2002.

In response, on February 11, 2002, Abdulaziz Muhammad Saleh bin Attash became one of 17 suspected terrorists added by the FBI to the "Seeking Information" list. The early version of that list was then known as the "Most Wanted Terrorists Seeking Information" list.

But on February 14, 2002, several days after the FBI alert, Abdulaziz Muhammad Saleh bin Otash was one of six names who were removed, and the FBI re-published the list as only eleven names and photos, because it was discovered that confusion over transliteration had failed to reveal initially that the removed six wanted terrorists were already in prison in Yemen.

The other names among the six identified in the Yemen plot on February 11, 2002, but who were removed from the list on February 14, 2002 as already in Yemen custody were: Issam Ahmad Dibwan al-Makhlafi, Ahmad al-Akhader Nasser Albidani, Bashir Ali Nasser al-Sharari, Shuhour Abdullah Mukbil al-Sabri and Riyadh Shikawi.

Whether foiled, aborted, or merely incorrect specific intelligence, the February 12, 2002 attack never occurred. However, other attacks and plots in Yemen soon followed in that year. By 2004, many of those plotters had also been captured and imprisoned in Yemen.

On October 12, 2000, one year prior to 9/11, Yemen became an early theater in the War on Terrorism, when the 2000 USS Cole bombing killed 17 American sailors and wounded 40 off the port coast of Aden, Yemen. In the aftermath, the government of Yemen rounded up numerous suspected terrorists, many of whom were identified as members of al-Qaeda.

The prisoners had initially gone unnoticed until Yemeni officials told the CIA station chief in San'a, Yemen's capital, that some of the men the FBI wanted were already being held. The FBI reported that agents had years earlier questioned some of the six men in connection with the USS Cole bombing in the port of Aden in October 2000. Because of the new information about the association to al-Rabeei, the FBI intended to again question the Yemen inmates.

Abdulaziz Muhammad Saleh bin Attash (Arabic: ), (born in 1975 in Saudi Arabia, and identified as a Yemeni - died in 2011), became briefly wanted in 2002, by the United States Department of Justice's FBI, which was then seeking information about his identity and whereabouts. In early 2002, he had been named in a suspected Yemen plot, for which he became listed on the FBI's third major "wanted" list, now known as the FBI Seeking Information - War on Terrorism list. He was identified as a known associate of the Yemen cell leader, Fawaz Yahya al-Rabeei. But he was quickly discovered to already be in Yemen prison, and was promptly removed from the FBI "wanted" list. He was the brother of Walid bin Attash and Hassan bin Attash.
