Polish Prime Minister Donald Tusk announced the arrest of an agent from Belarus and the expulsion of a diplomat for espionage activities against Poland.

Poland has arrested a Belarusian agent, Uladzislau N, accused of espionage, following cooperation with the intelligence services of Romania, the Czech Republic, Hungary, and Moldova. Prime Minister Tusk also announced the expulsion of a Belarusian diplomat involved in aggressive activities. Relations between Poland and Belarus are tense, and European intelligence services have dismantled a Belarusian espionage network. In Romania, the former deputy director of the Moldovan intelligence service, Alexandru Bălan, is being investigated for treason for transmitting state secrets to the Belarusian KGB. The Czech Republic has also expelled a Belarusian diplomat for espionage.
