A U.S. senator, leading a congressional delegation to the Armenia-Azerbaijan border on Saturday, said international observers were needed to monitor the situation in Nagorno-Karabakh, adding that people were "very fearful" about what was happening there.
"I am certainly very concerned about what's happening in Nagorno-Karabakh right now, I think there needs to be some visibility," Gary Peters, a Democrat from Michigan, told reporters on the border.
