US State Department spokeswoman Jennifer Psaki recently expressed her concern about the new round of tension in the Nagorno-Karabakh conflict, which ignited in the mass shelling of border and frontline Azerbaijani villages by large-caliber weapons on January 3.
"We are troubled by reports of ceasefire violations, as well as casualties in recent days," the official website of the State Department quoted her as saying.
She also called on Armenia and Azerbaijan to resolve the conflict through peaceful negotiations mediated by the OSCE Minsk Group. "We do continue to urge both sides at the highest levels to engage in negotiations that could lead to a peace agreement," she said, adding that the issue is in the spotlight in the USA.
