As many as 3,470 Syrians crossed the border in Jordan over the past week, said media spokesperson of the Higher Committee for Syrian Refugee Affairs in Jordan Anmar al-Hamoud. In press statements Friday, he said all refugees were moved to the Zaatari camp. He said 5,215 Syrians have voluntarily returned to their homeland over the past week. Jordan says it is hosting more than 500,000 Syrian refugees and the UN expects that number to soar to 1.2 million by the end of 2013 -- equivalent to a fifth of the kingdom\'s population.
