Poland is to expel the defence attache of Belarus, the Polish Press Agency reported on Thursday, citing a foreign ministry spokesman.
Last Friday, Belarus ordered the expulsion of three Polish diplomats, including a border guard liaison officer, in response to Poland’s closure of one of two truck border crossings.
Poland has been an important refuge for opponents of Belarus President Alexander Lukashenko, and is a staunch supporter of Ukraine since Belarus' main ally Russia invaded in February 2022.
