BAHAI, Chad, February 27. UNHCR Goodwill Ambassador Angelina Jolie on Tuesday completed a two-day mission to a refugee camp in eastern Chad which enabled her to assess how the security situation has deteriorated for Sudanese refugees since her last visit to Chad three years ago. Jolie, who visited both Chad and neighbouring Sudan's Darfur region with UNHCR in 2004, said she was struck by the sense of hope she encountered at the Oure-Cassoni camp near this town and by the widespread desire for peace-keepers to be deployed in Chad. She also reflected on the hardship and suffering she had seen at the camp, which is located less than five kilometres from the border with Sudan. "It's always hard to see decent people, families, living in such difficult conditions," she said. "What is most upsetting is how long it is taking the international community to answer this crisis," Jolie added.
