Poland, Ukraine to sign security agreement before NATO summit in Washington - Tusk 

Tusk said this at a press conference after a European Council meeting in Brussels, RMF24 reports.

"Our agreement is almost complete... I can say that we will sign this agreement together with President Volodymyr Zelenskyy in Warsaw before the NATO summit," Tusk said, adding that he needed to "think very carefully together with the Minister of National Defense how Poland can continue to help Ukraine."

"But in no way do we want to and cannot weaken Poland's defense capabilities. There are still some details to be worked out," he said.

The Polish prime minister also said he reassured Ukrainian President Volodymyr Zelenskyy that Warsaw would help Kyiv.

"I said it very clearly: we will help, because your security is our security, but we will not do anything that will weaken our immediate security, that is, our capabilities. We are talking about soldiers, about weapons, which are sometimes as necessary for Poland as for Ukraine," Tusk said.

• On June 27, President Volodymyr Zelenskyy signed a number of agreements on security guarantees for Ukraine with the EU, Lithuania, and Estonia in Brussels.
