African migrants hold signs during a protest at Rabin Square in Tel Aviv January 5, 2014. About 10,000 African migrants, largely from Sudan and Eritrea, protested in central Tel Aviv on Sunday against Israel's slow processing of asylum requests and arrests of hundreds under an Israeli law, approved last month and contested by human rights groups, which entitles the authorities to detain migrants lacking valid visas without charges.
