Fighting between Kyrgyzstan and Tajikistan that left at least 81 civilians and soldiers dead had subsided on Sunday, Kyrgyz authorities said.
The confirmation of casualties from both sides follows a ceasefire announced on Friday.
Russia : Russian President Vladimir Putin, whose government presides over a security co-operation organisation between the countries, called for an end to the violence in a statement on Sunday.
The dispute between the Russia-aligned states must be resolved through “peaceful, political and diplomatic means”, Mr Putin said.
The latest violence between the former Soviet republics, which began on Wednesday, is the worst fighting between the two rivals since May 2021.
The flare-up follows clashes between former Soviet states Armenia and Azerbaijan over the disputed Nagorno-Karabakh region.
Tajikistan and Kyrgyzstan dispute nearly 1,000 kilometres of border.
Kyrgyzstan, Tajikistan and Armenia are part of the Moscow-led Collective Security Treaty Organisation, sometimes dubbed “Russia’s mini Nato”, tasked with peacekeeping and security cooperation between former Soviet states.
Tajikistan said on Sunday that 35 of its citizens were killed, the first official death toll since armed clashes broke out on Wednesday.
On its Facebook page, the Tajik foreign ministry also reported 25 injured and said civilians, women and children were among the victims.
