A Syrian refugee stands in a refugee camp in al-Qaim, Anbar province, September 8, 2012. Al Qaim, in the Sunni heartland of Anbar province, reflects the tricky balancing act Iraq's Shi'ite leaders face in Syria, whose crisis is testing the Middle East's sectarian divide. Al Qaim and its neighbouring Syrian counterpart Albu Kamal are on a strategic supply route for smugglers, gun-runners and now insurgents aiming to join the rebellion. Picture taken September 8, 2012.
