Ukraine needs more air defenses to protect its grain exports and areas bordering Russia, President Volodymyr Zelensky said todayspeaking in Kyiv at an international summit on food security.

“There is a shortfall in air defense and it’s no secret,” Zelensky told the meeting of the “Grain for Ukraine” group, attended by senior officials from European countries, including Swiss President Alain Berche and Lithuanian Prime Minister Ingrida Simonite.

Overnight Russia launched an attack with 75 drones in Ukraine, the largest such attack since the start of the war. Earlier, the three leaders’ joint press conference was interrupted when air raid sirens sounded in Kiev.

Zelensky said that Ukraine’s foreign partners will provide it with vessels that will accompany cargo ship convoys sailing from Ukrainian ports, taking care of their safety. He added that Kiev hopes to solve the problem of insufficient air defense through new supplies from its partners but also by increasing its own production, which he assured there has been progress.

“I can’t give details today about what we are doing and where, but there is progress,” he said.

When asked about the mobilizations of Polish and Slovak truck drivers that have blocked the road transit of Ukrainian products in recent days, Zelensky blamed the internal politics of the two neighboring countries. “I think there are difficulties at the border first and foremost because of some policies implemented by our neighbors,” he said, expressing confidence that the problem would be resolved if neighboring countries were given “some time” to deal with the situation.
