Available for over a year

Despatches from correspondents: Why should the west intervene with aid or arms? It's a question asked by our reporter in northern Iraq. The six-year-olds in Gaza who've already lived through three wars. Awesome sights and stressful moments as the Panama Canal celebrates its centenary. Why did she pack an orange bottle of cleaning fluid along with the tennis shoes? Our correspondent talks of a frantic shopping run before her return to Cuba.
