SEATTLE - At least five people were shot, one of them fatally, Friday afternoon at the Jewish Federation of Greater Seattle, and one person was arrested, authorities said.

The assailant told building staff members before he began shooting that he was "a Muslim-American" who was "angry at Israel," the Seattle Times reported, citing Amy Wasser-Simpson, a federation vice president.

FBI Agent Frederick Gutt declined to confirm a motive.
