As we read on the website of the Komenda Powiatowa Państwowej Straży Pożarnej w Bolesławcu:
Colleagues! We lost two brave firefighters in the line of duty in Białystok. They left behind two young children. The Dorastaj z Nami Foundation is collecting donations for their families. A donation can be made through the Foundation’s website or directly by transferring funds to account no. 29 1030 1508 0000 0008 1545 4006, with “Białystok” in the payment reference. Thank you for every contribution.
