BROOKLYN - It's now been 50 years since President John F. Kennedy was assassinated while riding in his motorcade in Dallas, Texas.

Flags were flown at half-staff and ceremonies were held nationwide to mark the solemn anniversary.

Some residents visited Grand Army Plaza, where a statue sits in his honor with a quote from the inaugural address he delivered in Jan. 1961. The statue was proposed by former Brooklyn Borough President Abe Stark shortly after the 35th president's death.

Up in Boston, a small exhibit of never displayed items from Kennedy's funeral was shown at the JFK Library and Museum.

Earlier this week, President Barack Obama visited Kennedy's grave at Arlington National Cemetery for a special wreath-laying. Obama spent the anniversary meeting privately at the White House with leaders and volunteers from the Peace Corp program that Kennedy had created.

A moment of silence across the entire country was held at 12:30 p.m.
