The Armenian National Security Service is investigating information provided by Baku, alleging that one of the Azerbaijani border checkpoints has been attacked.

"The State Border Guard Service of Azerbaijan provided information to the Armenian side that one of their checkpoints has been attacked," the NSS said in a statement on Friday, August 27.

The Security Service said the Armenian and Russian sides continue negotiations with the Azerbaijani military to open an interstate road that has been blocked by the Azeris in the past three days.

The National Security Service confirmed on Thursday that the Armenian side is working to restore traffic on Karmrakar-Shurnukh section of the Kapan-Goris highway blocked by the Azerbaijani side since Wednesday evening. Tatoyan revealed later in the day that the Azerbaijani military has blocked another section of an interstate road in the same area.
