LOS ANGELES (AP) — Standing before a steel girder from the World Trade Center, Los Angeles officials marked the anniversary of the Sept. 11 attacks with speeches, a bell ringing ceremony and a rendition of "Taps."

Police Chief Charlie Beck called 9/11 "a day of horror and infamy."

Law enforcement helicopters flew over the ceremony Wednesday at the LA Fire Department training center in Elysian Park

It was one of many similar events across Southern California.

In Malibu, the lawn at Pepperdine University is adorned with nearly 3,000 flags, each representing the nationality of each victim of the attacks 12 years ago.

Before an evening game against the Arizona Diamondbacks, the Dodgers will pay tribute to first responders by unfurling a 9/11 flag from the New York Says Thank You Foundation in center field.
