EU Leaders to push for difficult Turkey migrant deal

European Union leaders have begun a difficult summit to push for a crucial agreement with Turkey to curb the continent's massive migration crisis despite threats by Cyprus to sink the deal.The plan proposed by Ankara last week to a desperate, divided Europe was hailed by German Chancellor Angela Merkel on Wednesday. Angela described it as the "first real chance" to end the influx of refugees and migrants.But the ambitious proposal, under which Turkey would take back all asylum seekers arriving in Greece, faces heavy criticism on several fronts.
