ROMANS: Tens of thousands of Syrians desperately fleeing to the Turkish border to escape what the U.N. is now calling extermination. Syrian government forces backed by relentless Russian air strikes are driving them from their homes in Aleppo. And now, a U.N. report accuses the Assad regime of inhumane actions against civilians, Syrian civilians. I want to bring in senior international correspondent Arwa Damon live along the turkey/Syrian border. Good morning, Arwa.</s>ARWA DAMON, CNN SENIOR INTERNATIONAL CORRESPONDENT: Good morning. And another important aspect highlighted in that U.N. report is that more people, civilians, have been killed by the Assad regime than by ISIS or any of the other opposition groups or by any of the Russian and coalition airstrikes. Tens of thousands already gathered here on the other side of the border crossing, awaiting for Turkey to decide that the condition will allow them to cross through. What does this mean? Well put simply, Turkey says it cannot take anymore refugees. It already has more than 2.5 million. It is providing shelter, food, water for them on the other side. But those who are stuck are really just begging with the authorities to have mercy and let them through, because they don't necessarily care about having a tent over their heads. What they want so desperately is the sense of security in the face of what many are describing as the most intense bombardment of the Syrian civil war. That is the bombardment by Russian jets that are providing significant air cover for Assad's forces clearing out not only areas in the Aleppo countryside, but also advancing what was once Syria's largest city.</s>ROMANS: All right. Arwa Damon, thank you so much for that. Arwa Damon on the Turkey/Syria border for us this morning, where all of those people are just caught. Thank you. Happening now, New Hampshire voters heading to the polls. This is the nation's first presidential primary. Oh, yes, it's here. Candidates there making a flurry of last minute attacks. We've got that next.
