Youssou N'Dour pays tribute to Bob Marley

You’ve heard the statistics about drug violence deaths along the US-Mexico border – more than 70,000 lives lost in the last six years alone. Acclaimed journalist Ed Vulliamy spent years travelling the frontier to write his book "Amexica". He takes us behind the scenes and tells Catherine Nicholson why he thinks we’re all implicated.

David Bowie’s hotly-anticipated new album "The Next Day" has lived up to the hype with critics and fans, scoring the veteran musician his first number one UK chart placing since 1993. We also meet Iraq war veteran-turned-novelist Kevin Powers, who put his recollections to paper in "The Yellow Birds". And the big movie release of the week is "Cloud Atlas". We ask whether stars Tom Hanks and Halle Berry can hold this "unfilmable" story together.
