The news comes after more than 1.2 million people have entered Poland after fleeing the conflict in Ukraine, according to the United Nations.
Is it safe to visit Poland?
Poland shares a 332-mile border with Ukraine and Nato has said it will strengthen its eastern flank along this.
From 2 March 2022, Poland extended a law limiting access until 30 june 2022 to areas within approximately three kilometres of the Belarusian border, in parts of Podlaskie and Lubelskie Voivodeships.
The UK Foreign, Commonwealth and Development Office (FCDO) is not currently advising against travel to Poland, but warns that visitors may notice some effects of the Russian invasion as refugees flee to the country to seek shelter from the conflict in Ukraine.
The Polish government has said it will house Ukrainian refugees in hostels, dormitories and sports facilities.
The FCDO states: “You should not attempt to cross into Ukraine from Poland.
“You should abide by the instructions of the authorities at all times.
“If you have arrived in Poland from Ukraine and are in need of assistance, you should call +48 22 311 00 00 and select the option for “consular services for British nationals.
“You can also send an enquiry via the web contact form.”
