Polish Prime Minister Donald Tusk offered help in tackling the deadly wildfires in Central Russia, his office said, RIA Novosti reported.
Poland was ready to "render comprehensive aid in dealing with the wildfires and their aftermath," Tusk said in a letter to his Russian counterpart Vladimir Putin.
"In connection with the wildfires which have devastated vast swaths of the Russian Federation... and resulted in many deaths, I ask [you] to accept my sincere condolences and deep sympathy," the Polish prime minister added.
A scorching heat wave has gripped much of European Russia since mid-June, sparking wildfires and causing the worst drought in decades.
A total of 376 hotspots from wildfires have been registered in 17 Russian regions, and the state of emergency has been declared in seven of them. At least 48 people were killed and over 3,500 displaced as a result.
