Â鶹ԼÅÄ

Syrian refugees in Lebanon are being handed cash cards instead of blankets and food. Aid agencies say money transfers are a better way to deliver essential supplies to some of the 1.5 million Syrians who live in the country – they buy what they need themselves. But does it work? We meet Moussa Junaid, who fled Raqqa with his family when IS moved in, and now buys food aid for himself from the local supermarket.

Plus, a very big idea about how the US could handle mass shootings differently. And, we help out Ugandan student Martin, who gets woken every night by the motorcycle taxis outside his window.

World Hacks is a new Â鶹ԼÅÄ programme that meets the people who are attempting to fix some of the world’s biggest problems. Then we figure out whether their solutions actually work.
