the hungarian/serbian border. >> we heard of one woman whose husband had a heart attack five days ago. he was taken to the hospital and shep doesn't know if he's alive or dead. there's a vast situation here at the border. and one of the problems is the hungarian authorities don't want to ask for assistance to treat the people properly. they have no interpretors or doctors. nothing to treat the people in the humane way. >> the migrants are trying to make it to hungary before this fence is finished along the hungarian border. they hope to have the barbed wire fence done by october. it is 4 meters high. it is shaping up to be the most controversial crisis.
