A Deadly Dilemma
Are international regulations designed to stop money and equipment reaching terrorist organisations curtailing vital aid programmes in some of the world's most troubled regions?
In many parts of the world, charities are trying to deliver much-needed aid to desperate people living in areas controlled by militant groups. What do they do when counter-terrorism laws ban them from contact with those de facto authorities?
Risk of prosecution has now created a climate of fear in many aid agencies - and the UN wants counter-terrorism policies redrawn to ensure lives can be saved without charity workers risking jail.
Tim Whewell reports from Gaza - and talks to aid workers operating in Syria, Somalia and other places - on the practical and moral dilemmas involved.
