Tuning in for a whistling contest

The world's best whistlers descended on the Los Angeles suburb of Pasadena for a special contest.

They were taking part in the Masters of Musical Whistling International Festival and Competition.

"Here we have over 60 whistlers from 11 countries, from all over the world," said competition organiser Carole Anne Kaufman, a former world champion whistler.

"We are talking from Japan, from Spain, from Italy, we have people coming from all over. It is very exciting to see just so many people that are coming together to be a part of the community.

"What makes a good whistler is the same thing that makes an excellent instrumentalist. So, we are looking for the people that sound beautiful, they are in tune, they know how to perform, to connect with the audience.

"Whatever you would expect from your favourite opera star, whatever you would expect from a professional saxophone player who can do something that moves you, that is how we are judging you, that's what makes a world champion."

Havana laugh

Children splashed inside a mobile pool in the El Infernal neighbourhood in the province of Pinar del Rio, part of Cuba's renowned tobacco-growing zone.

The makeshift pool made from a cart hitched by a tractor is among the latest attraction for children seeking a reprieve from the harsh Caribbean heat.

In a neighbourhood far from recreation centres, community members helped to make the idea of the tractor pool a reality, lending tarps, providing water and paying for the tractor's gasoline.

"We dream that our children do not move to another community, but that they become the new farmers of the future. That is why we provide this," said Ipolito Marraron, the president of the cooperative that lent the tractor, with the condition that it could only be used if it wasn't needed by the agricultural workers.

Almodovar award

Spanish filmmaker Pedro Almodovar has been given a lifetime achievement award at the Venice Film Festival.

The 69-year old Oscar winner is best known for films like "Talk to Her", "Volver" and most recently loosely autobiographical portrait "Pain and Glory".

Spanish food fight

Thousands of revellers hurled tonnes of tomatoes at each other on Wednesday (August 28), cavorting in the red pulp beneath their feet in the Spanish town of Bunol.

Some revellers wore goggles to protect their eyes and some buildings were draped with tarpaulin to preserve their walls, while others got soaked with the pulp, creating a scene worthy of a modern art painting.

The Tomatina is said to have originated from a spontaneous bust-up amongst villagers in 1945.

It was banned for a while during the 1950s at the height of General Francisco Franco's dictatorship but survived to gain popularity across Spain in the 1980s and today draws large crowds of visitors from abroad as well as Spaniards.

The town hall distributed more than 20,000 tickets to the festival this year.
