Britain announced on Thursday that it would send military experts to Bosnia and Herzegovina to “reinforce the NATO Mission and promote peace and security” in the nation, as well as to counteract Russian influence.

“We cannot allow the Western Balkans to become another playground for (Russian President Vladimir) Putin’s pernicious pursuits. By fanning the flames of secessionism and sectarianism Russia seeks to reverse the gains of the last three decades in Bosnia and Herzegovina,” Prime Minister Boris Johnson said in a statement.

“That is why we are stepping up support to Bosnia and Herzegovina, answering the call from our friends to help protect the peace they so rightfully deserve to enjoy.”
