Armenia's Prime Minister Nikol Pashinyan said on Friday that 135 Armenian service personnel had been killed in clashes with Azerbaijan this week, the Interfax news agency reported from a session of Armenia's parliament.
Pashinyan on Wednesday said 105 soldiers had died and that the figure was likely to rise.
Both Baku and Yerevan blame each other for this week's fighting - the deadliest clashes between the two countries since a six-week war in 2020 left thousands dead.
