Sources name hijacking suspects

Investigators inspect the scene of the Flight 93 crash in western Pennsylvania.

(CNN) -- CNN has learned from federal law enforcement sources the names used by 18 hijackers who authorities believe commandeered four commercial airliners on Tuesday in a coordinated attack on two renowned symbols of American power.

The suspected hijackers aboard American Airlines Flight 11, which hit the north tower of the World Trade Center, were Walid Al Shehri, Wail Alsheri aka Waleed Alsheri, Mohammad Atta, Aabdul Alomari and Satam Sugami.

Aboard United Airlines Flight 175, which hit the south tower of the World Trade Center, the suspected hijackers were Marawn Alshehhi, Fayez Ahmed, Mohald Alshehri, Hamza Al Ghamdi and Ahmed Al Ghamdi.

Those believed to be the hijackers aboard American Airlines Flight 77, which hit the Pentagon, were Khalid Almihdhar, Majed Moqued, Nawaf Al Hazmi and Salem Al Hazmi.

The suspected hijackers aboard United Airlines Flight 93, which crashed in rural Pennsylvania, were Ahmed Al Haznawi, Ahmed Alnami, Ziad Jarrah and Saeed Alghamdi.

Spellings are as they appear on federal documents and may vary from other spellings used.

Law enforcement sources told CNN that they are checking the names against lists of people associated with known terrorist groups -- and believe the lead group in Tuesday's attacks may have been Egyptian Islamic Jihad.

The chief of that group, the sources said, is a top lieutenant of suspected terrorist Osama bin Laden. Bin Laden's group, Al Qaeda, is an umbrella group that reportedly coordinates the actions of smaller organizations.

As President Bush prepared to see for himself the devastation inflicted on lower Manhattan, the Defense Department asked that 50,000 reservists join the military effort that follows the coordinated terrorist attacks four days ago on the United States, CNN has learned. (Full story)

Bush designated Friday a day of "National Prayer and Remembrance," and asked that Americans head to their places of worship at lunchtime to pray for victims and their families. The president planned to attend a service at the National Cathedral in Washington before traveling to New York. Former Presidents Clinton, Ford and Carter were also expected to attend.

Many European nations observed three minutes of silence at 6 a.m. EDT. (Full story)

The Defense Department will seek authority to call up the military reservists for "homeland defense." Officials at the Pentagon tell CNN the callup would reinforce warplane patrols of American skies to defend military bases and any other possible targets against attack. Governors in 31 states have already called up 10,000 National Guard troops.

A pair of hijacked commercial airliners plowed into the twin towers of the World Trade Center on Tuesday, followed a half an hour later by another hijacked jet that hit the Pentagon in Washington. A fourth jet hit the ground in rural Pennsylvania. (Full story)

There is no question that Osama bin Laden has been -- for many years now, by his own pronouncements -- anti-West, anti-U.S., anti- a number of regimes in the Arab world."
