The UN says donors at a fund-raising conference in Kuwait have helped it raise more than its target of $1.5bn for Syrian humanitarian assistance. The aim of the conference was to help those suffering inside Syria, and the refugees in neighbouring countries - a figure that now stands at more 700,000. Ban Ki-moon, the UN secretary general, called the situation in Syria a humanitarian catastrophe that was growing by the day. Al Jazeera's Diplomatic Editor James Bays reports from Kuwait City.
