Reports of repeated incidents along Armenia-Azerbaijan border causes grave concern, OSCE Chairperson-in-Office Ann Linde said in a tweet on Thursday July 29.

Linde urged the sides to build on recent humanitarian steps and implement the November 9 statement in full to address unresolved issues peacefully.

In the wee hours of July 28, the Azerbaijani armed forces attacked the Armenian positions in Gegharkunik province, triggering local battles. Three Armenian troops were killed, five others were wounded in the process, the Defense Ministry said, adding that the Azerbaijani forces have been thwarted back to their positions. The Azerbaijanis fired on Armenian positions on July 29 too, injuring one more soldier.
