Human Rights Watch reports border guards in Iraq, Jordan and Turkey are rejecting tens of thousands of refugees attempting to flee the conflict in Syria. The groups says only Lebanon is keeping its border with Syria open, while Syria’s other neighbors are either rejecting refugees outright or allowing only a limited number in, leaving many stranded at the border. Turkey has rejected the accusations, saying it is currently hosting more than 200,000 Syrians in refugee camps. The report comes amid reports of a government siege on the central city of Homs and of the killing of a Syrian Roman Catholic priest by rebels in the north.
