"We have 14 brigades who do not have the necessary weapons that have already been approved and discussed," Zelensky said.Washington, Kyiv's leading military donor, approved in April a long-expected $61-billion aid package after months of delays. In spite of this, Russia has continued to pressure Ukraine along the front, launching a new offensive in Kharkiv Oblast and steadily pushing into a key town of Chasiv Yar in Donetsk Oblast."The (assistance) packages should arrive, but they are coming slowly," the president said, adding, "We are grateful to Congress for its support."Zelensky said that, nonetheless, the situation cannot be described as a stalemate and that the current difficulties can be solved with appropriate tools, referring to foreign military aid.The head of state said that, at the moment, it is not appropriate to talk about a Ukrainian counteroffensive as Kyiv must focus on protecting what it has.
