PIERRE, S.D. (AP) — Flags on public buildings in South Dakota will remain at half-staff Monday in honor of the victims of the attacks on Pearl Harbor 74 years ago.

The directive from South Dakota Governor Dennis Daugaard is in accordance with a proclamation from President Barack Obama. Monday has been designated as National Pearl Harbor Remembrance Day.

The surprise attack by Japan on December 7th, 1941 on the U.S. Navy base at Pearl Harbor in Hawaii claimed some 2,400 American lives and pushed the U.S. into World War Two.

Flags in South Dakota are already at half-staff. They were lowered last week to honor the 14 people killed in a shooting Wednesday at a social service center in San Bernardino, California.
