KYIV, May 5 - Ukrainian forces said Thursday they made some gains on the border of the southern regions of Kherson and Mykolayiv and repelled 11 Russian attacks in the Donetsk and Luhansk regions that make up the Donbas.

The Washington-based Institute for the Study of War said that Ukrainian forces “have largely stalled Russian advances in eastern Ukraine,” and intensified Russian airstrikes on transportation infrastructure in the western part of the country have failed to stop Western aid shipments to Ukraine, The Associated Press reported.

But the war has devastated the country’s medical infrastructure, President Volodymyr Zelensky said in a video link to a charity event in the U.K., with nearly 400 healthcare facilities damaged or destroyed.

“There is simply a catastrophic situation regarding access to medical services and medicines,” in areas occupied by Russian forces, he said. “Even the simplest drugs are lacking.”

With the challenge of mine-clearing and rebuilding after the war in mind, Zelenskyy announced the launch of a global fundraising platform called United24.

At the same time, Poland hosted an international donor conference that raised $6.5 billion in humanitarian aid. The gathering was attended by prime ministers and ambassadors from many European countries, as well as representatives of nations farther afield and some businesses.

In addition, a Ukrainian cabinet body began to develop proposals for a comprehensive postwar reconstruction plan, while Zelenskyy also urged Western allies to put forward a program similar to the post-World War II Marshall Plan to help Ukraine rebuild. (ap/ez)
