The Polish border blockade has led to problems with the supply of military supplies to the front line, The New York Times reports.

Soldier Oleksandr, who is fighting in the east, told the publication that his unit is still waiting for the delivery of two night vision devices that are stuck at the border. These devices are crucial for the safe advancement of soldiers to combat positions.

"In order to block the country's borders during a full-scale invasion, they must be completely detached from reality, and in doing so, they also wash their hands in the blood of people who are waiting for the necessary help," he said.

The publication writes that the blockade could lead to a 1% drop in Ukraine's projected GDP growth in 2023, according to Yulia Klymenko, head of the parliamentary committee on transport and infrastructure.

"Enterprises do not receive enough components; supply chains are disrupted. This also applies to military equipment and its production." To even assemble drones in Ukraine, they need to be brought from somewhere else," Klymenko said.
