Crossing a St Louis street that divides communities

The city of St Louis, Missouri, remains one of the most segregated cities in the US, according to a study by the Manhattan Institute. But one street in particular has been known to residents as the "dividing line".

Delmar Boulevard, which spans the city from east to west, features million-dollar mansions directly to the south, and poverty-stricken areas to its north. What separates rich and poor is sometimes just one street block.

The BBC's Franz Strasser talked to residents, business owners and pastors on both sides of the street about why things are the way they are.
