Poland hopes to bring in border guards and police from Finland, Germany, and Greece to help patrol its frontier with Belarus, a senior official said on July 4, amid mounting concerns over migration pressures from the east into Europe. "Preparations are underway and these are countries that are very experienced in border protection. Especially, for example, Greek experiences can be very useful," a senior government official told reporters. The border between Poland and Belarus has become a flashpoint as Western officials accuse the government in Minsk of using migrants it brings from in from outside of Europe as "hybrid warfare."
