Exodus From Nagorno-Karabakh

Kate Adie presents stories from Nagorno-Karabakh, Canada, South Africa, Peru and Germany. Tens of thousands of ethnic Armenians have fled the disputed enclave of Nagorno-Karabakh in the last week. Rayhan Demytrie spoke to some on the Armenian border about the devastating impact of the recent Azeri blockade. And now they face the loss of their homeland, with distrust between both communities running deep. Canada's assertion that India appears to have been involved in the murder of a Canadian Sikh has sparked outrage in New Delhi and beyond. The Indian government has strongly denied the allegation. In Vancouver, Neal Razzell visits the Sikh temple where the dead man, Hardeep Singh Nijjar was leader, and found out more about what happened on the fateful day. A fire in Johannesburg at the end of August threw into sharp relief the terrible conditions in some affordable housing, which is often taken over by gangs who illegally rent out the buildings. Samantha Granville spoke to residents of the site that burned down, along with others in similarly precarious accommodation. In Peru's capital Lima, around 2 million residents living in the poorer suburbs have no access to running water and have to pay high prices for it to be delivered to them. Peter Yeung met someone who has come up with an innovative solution: an improvised canal system which collects water from the clouds - known as 'fog-catchers'. And finally, in Germany, a campaign is being launched to change a law that sees thousands of people sent to prison every year for travelling on public transport without a ticket. Tim Mansel meets one man helping to get people released because they haven't paid their fine.
