Early warning missile alert for Syrian civilians

Like many Syrians who fled the war Dishad Othman has been watching it unfold from a far, but wanted to help civilians on the ground.

He has decided to put his military training and computer programming skills into use and has now set up an early warning system that can alert people in Syria when a ballistic missile is coming their way.

Mr Othman told the BBC's World Service how he came up with the idea.
