The U.S. expects Azerbaijan to pull back all forces and call on both sides to demarcate their shared international borders.

A total of 3503 tests have been performed in the past day, the National Center For Disease Control and Prevention said.

Makunts said the troops were "abducted", as the Defense Ministry said earlier that the soldiers were on Armenian soil.

The Defense Ministry said all necessary measures are being taken to ensure the return of the captured military servicemen.
