An African refugee walks outside his temporary shelter in Tel Aviv, Israel on 20 February 2008. Israeli police said on February 26 that they have arrested around 200 illegal African immigrants during a sweep of a working class district around the Mediterranean city's old central bus station. In recent months, dozens of migrants, most of them Africans, have been arrested and some shot dead in Egypt as they tried to make their way across the border. The government last year decided to grant residency to around 500 refugees from Sudan's war-torn region of Darfur after months of public debate, but not to other Africans who had entered illegally from Egypt.
