Northrop workers killed in attack

Nine employees of Northrop Grumman Corp.'s subsidiary Vinnell Corp. were killed in the May 12 suicide bombings in Riyadh, Saudi Arabia.

Northrop Grumman officials confirmed that the employees were among those killed in the attack, but declined to disclose their identities.

According to the Washington Post, the coordinated bombing attack destroyed homes and buildings in three locations and killed at least 29 people, including nine attackers. More than 190 were injured and many of them may not survive, the Post reported.

The Vinnell employees included seven U.S. citizens and two from the Philippines. Another 15 employees remain hospitalized from injuries suffered in the attacks.

"We are deeply shocked by this senseless attack and mourn the loss of our colleagues," said Donald Winter, corporate vice president and president of Northrop Grumman Mission Systems, in a statement. "We continue to work closely with the U.S. government to secure the safety of all company employees and their dependents in Saudi Arabia."

Vinnell Arabia is under contract to the U.S. Army to provide training services to the Saudi Arabian National Guard. The company employs about 800 people in Riyadh, 300 of them American.
