Ukraine warns that the Russians are stealing Ukrainian grain, and any country who buys the stolen grain from Russia is considered to be "complicit in the crime." It warned of legal consequences for everyone involved in the transportation and sales of the stolen grain.
Meanwhile, the former president of Russia has warned NATO that military assistance for Ukraine risks sparking a wider conflict.
Dmitry Medvedev, a close ally of President Vladimir Putin, said the supply of weapons to Ukraine "increased the likelihood of a direct and open conflict between NATO and Russia instead of their 'war by proxy'."
It comes after European Commission President Ursula von der Leyen said Russia was the "most direct threat" to the international order.
Elsewhere, Finland's President Sauli Niinisto and Prime Minister Sanna Marin said this morning that the country should apply to join NATO "without delay."
The U.S., meanwhile, plans to send a delegation led by Secretary of State Antony Blinken to NATO's meetings in Berlin this weekend.
