A note in return to an analogous Belarusian step was Friday handed to the Belarusian Foreign Ministry by Lithuania's Ambassador to Minsk Andrius Pulokas, the Lithuanian Foreign Ministry said.
"The note expresses regret over the incident and assures that the State Border Guard Service of the Republic of Lithuania would take all the necessary measures to prevent analogous incidents from happening in the future," reads the press release.
The note admits that Lithuanian border guards on September 28 illegally entered the neighboring country's territory on the line of duty at the international border checkpoint Lavoriškės-Kotlovka.
The Lithuanian State Border Guard Service said the officers entered Belarus while pursuing suspected border offenders.
Belarus said the armed Lithuanians had walked around 40 meters into its territory.
