Poland has accepted over a million Ukrainian migrants, Prime Minister of Poland Beata Szydlo said Tuesday.

The prime minister did not specify the exact period of time during which this number of Ukrainian nationals arrived.

“Poland has already taken in about a million people from Ukraine,” Szydlo said at a plenary session of the European Parliament in Strasbourg, as broadcast by the European commission’s website.

Warsaw saw an influx of hundreds of thousands Ukrainian refugees in 2015 as Ukraine suffered a military conflict.

In May 2015, the Center for Eastern Studies (OSW) thinktank said that there were up to 400,000 migrants from Ukraine in Poland.

More than a million Ukrainians have sought asylum or other forms of permission to remain legally in other countries since the beginning of the military operation in Donbass in April 2014, according to the UN High Commissioner for Refugees.
