The world's largest military fair is wrapping up in the United Arab Emirates. The IDEX exhibition attracts mainly African, Arab and Asian officials who are shopping for weapons. For defence companies at the fair, it's a highly lucrative market. Never since the end of the Cold War have countries spent so much on defence, with deals worth a total of 100 billion dollars signed worldwide last year. Our correspondents report from Abu Dhabi.
