Syrian Tulin Hashemi waits for a job interview at a hotel in Vidigal slum in Rio de Janeiro, Brazil, September 22, 2015. Tulin, whose mother arrived two days ago, has been living in Brazil for two months. As she does not speak Portuguese, Tulin says it is difficult for her to find a job and therefore she is staying at the slum as it is one of the cheaper neighbourhoods to live in. According to the National Committee for Refugees (CONARE), 2,077 people fleeing the Syrian civil war have settled in Brazil, whilst a quarter of the 8,400 refugees in the Latin American country come from Syria.

Gold prices remained steady, boosted by prospects of increased demand due to its status as a safe haven in times of turmoil. (Photo by Manan Vatsyayana/AFP Photo)
