Ukrainian Foreign Minister Dmytro Kuleba Tuesday urged other governments to send more weapons more quickly to aid Ukraine’s fight against Russian forces.

“Too early to conclude that Ukraine already has all the arms it needs,” Kuleba tweeted Tuesday. “Russian offensive in the Donbas is a ruthless battle, the largest one on European soil since WWII. I urge partners to speed up deliveries of weapons and ammunition, especially MLRS, long-range artillery, APCs.”

Britain’s defense ministry said Tuesday that Russian forces have increased the intensity of their operations in the Donbas region in eastern Ukraine as they try to encircle multiple cities, including Severodonetsk.

“Russia’s capture of the Severodonetsk pocket would see the whole of Luhansk Oblast placed under Russian occupation. While currently Russia’s main effort, this operation is only one part of Russia’s campaign to seize the Donbas.”

Kuleba’s call for more military help came a day after U.S. Secretary of Defense Lloyd Austin said about 20 countries are sending new security assistance packages for Ukraine.

“Many countries are donating critically needed artillery ammunition, coastal defense systems, tanks and other armored vehicles. Others came forward with new commitments for training Ukraine’s forces and sustaining its military systems,” Austin told reporters at the Pentagon after concluding the second meeting of the Ukraine Defense Contact Group.

Denmark said it would provide Ukrainian forces with a Harpoon launcher and missiles, while the Czech Republic donated attack helicopters, tanks and rocket systems.

Monday’s meeting included 47 nations that participated virtually, according to Joint Chiefs of Staff Chairman General Mark Milley, the top U.S. military officer. Austria, Colombia and Ireland were among the new participants.

The group’s next meeting will be held June 15 in Brussels.

“Everyone here understands the stakes of this war, and they stretch far beyond Europe,” Austin said.

U.S. President Joe Biden had a similar message Tuesday as he met with the leaders of Japan, India and Australia, telling the group that the conflict in Ukraine “is more than just a European issue, it’s a global issue.”

Citing the widespread effects of the conflict, including on the global food supply, Biden pledged ongoing U.S. support, saying, “as long as Russia continues the war, the United States will work with our partners to help be the global response, because it’s going to affect all parts of the world.”

The American multinational chain of coffeehouses, Starbucks, became the latest company on Monday to announce it will stop operations in Russia, closing its 130 cafes. The move follows an announcement last week by U.S. multinational fastfood chain, McDonald’s, that it was leaving Russia.

Ukrainian President Volodymyr Zelenskyy said in his nightly video address Monday that Russia has launched almost 1,500 missile strikes on Ukraine since the start of the war nearly three months ago. He said the majority of the 1,474 missile strikes were against civilian targets.
