People from around the world gathered in New York's Greenwich Village on Friday to celebrate the 50th anniversary of the birth of the LGBT movement.

The anniversary marks the occasion on June 28, 1969, when patrons of Greenwich Village gay bar, the Stonewall Inn, rose up in defiance of police harassment.

The unrest triggered a national and global movement for equal rights for lesbian, gay, bisexual and transgender people.

Between four and six million people are expected to take part in the city's Pride Rally this weekend, which is part of a month-long Pride celebration commemorating the Stonewall uprising.
