Best pictures of the day

From workers cleaning the Atomium to a waitress carrying meals, here are September 28's best pictures.

Workers stand on one of the spheres of Brussels` Atomium during a site cleaning September 28, 2012. The 102-metre (335 feet) tall structure and its nine spheres symbolise a crystal molecule of metal with its atoms being magnified about 165 billion times.

The cleaning of the Atomium, which was designed for the 1958 International Exhibition of Brussels and which received a multimillion-dollar facelift in 2006, will run for a full month.

A team of five specialised workers take about three days to clean a ball, each of which has a surface area of 1000 square metres (10,764 square feet).
