Around 150,000 people attended a parade in Mexico City over the weekend organized by the municipal government to welcome summer 2011, officials said.

Different acts performed along the route of Sunday's parade, a Federal District Public Safety Secretariat spokesman told Efe, adding that 1,200 police officers were deployed to provide security.

No incidents were reported during the event, but some streets were closed for hours, the spokesman said.

About 1,500 people wearing different costumes participated in the parade, which was started with the wave of a flag by Mexico City Mayor Marcelo Ebrard.

The first-ever Great Parade was designed to provide entertainment for children and families, Ebrard said.

The parade wound its way down the Paseo de la Reforma, starting at the Glorieta de la Torre del Caballito and ending at the Torre Mayor.

Acrobats, clowns and angels performed along the parade route, while huge balloons of popular characters, such as Spiderman and Mickey Mouse, as well as traditional characters, including Cri Cri the cricket and La Catrina, soared overhead.
