BOSTON (WHDH) -- Ceremonies of remembrance began at 7:30 Tuesday morning in Boston.

Mayor Menino presided over a wreath-laying held in the public garden along with other public officials and the families of 9/11 victims.

Many towns and cities across the state participated in moments of silence at 8:46 and again at 9:03, the times each of the two planes that left from Boston flew into the World Trade Center towers.

"How do we work together that's the thing that's the most important thing is working together to make this a better world for all of us and to understand our differences also, that's how we do it and I think we're starting to realize that the issues of the past aren't the issues of the future. We all have to work together," said Menino.

Several events are scheduled across Boston to remember and honor 9/11 victims and heroes.
