Volodymr Zelensky criticised Joe Biden for not doing enough in allowing US weapons to be fired into Russia as Ukraine faces the threat of a renewed invasion.

The Ukrainian president thanked Mr Biden for giving Kyiv permission to strike inside Russian territory with American munitions, but said restrictions – including on the use of long-range Atacms – should also be dropped.

He said: “Is that sufficient? No. Why? Because I have given you the example of airfields from which Russia is permanently firing, in calm knowing that Ukraine will not fire back because it has no corresponding systems and no permissions.”

After weeks of pressure Biden gave permission for Ukraine to use American missiles like Himars to fire across the border north of Kharkiv, where Russian forces are massing. But he blocked Ukraine from using the more advanced Atacms systems.

Mr Zelensky said Russia continued to use artillery, long-range fire, and some 300 weapons systems carrying tens of thousands of missiles on its side of the border to target the Ukrainian population.

“So they have these weapons there and they do not remove them because they know that Ukraine cannot target them with Western weaponry even if they fire against us,” he said.
