US Secretary of State John Kerry, in separate calls on Thursday with the presidents of Armenia and Azerbaijan, urged them to avoid tensions in the Nagorno-Karabakh conflict zone, according to Reuters news agency.
The US Department of State said in a statement that Kerry noted that the ceasefire in Nagorno-Karabakh had largely held in recent weeks.
The US Secretary of State also asked the presidents to fulfill commitments they made to advance the peace process at a May 16 meeting in Vienna and a June 20 meeting in St. Petersburg.
