Passengers take a break while travelling on a SNIM train carrying iron ore and mine workers across the desert outside Nouadhibou June 25, 2014. Mauritania's SNIM iron ore mining company aims to produce 13 million tonnes in 2014, around the same level as last year, the majority state-owned firm said. SNIM mines black iron ore in the northern town of Zouerate, a remote desert location which nevertheless attracts people from all over the country looking for work. SNIM employees proudly call their firm the lung of their nation's economy and the train that ferries the ore to the coast stretches some two kilometres, making it one of the world's longest.
