As heavy artillery fire rocks the Syrian city of Homs, Matthew Bannister talks to a soldier who defected after being ordered to fire on anti-Government protesters.

Also in the programme, as the countdown to the Olympic Games continues, and as part of our "Edible City" series, a Ugandan-Asian woman based in London, cooks a dish that reminds her of home.

And we meet Thinlas Chorol, a young woman from Ladakh in the Himalayas who broke down barriers by becoming a trekking guide.
