The Dec. 7, 1941, bombing of Pearl Harbor  and those who lost their lives that day are being remembered Wednesday on the 70th anniversary of the Japanese attack that brought the U.S. into World War II.

About 120 survivors will join Navy Secretary Ray Mabus, military leaders and civilians to observe a moment of silence in Pearl Harbor at 7:55 a.m. Hawaii time - the moment the attack began seven decades ago.

About 3,000 people are expected to attend the event held each year at a site overlooking the sunken USS Arizona and the white memorial that straddles the battleship.
