Ukraine's allies have dramatically scaled back their pledges of new aid to the country, which have fallen to their lowest level since the start of the war, the Kiel Institute's Ukraine aid tracker showed.
"The dynamics of support to Ukraine have slowed," the German-based institute said, adding that new military, financial and humanitarian aid pledged to Ukraine between August and October 2023 fell almost 90% compared with the same period in 2022, reaching its lowest point since the start of the war in February 2022.
The figures come amid signs of growing cracks in Western support for Ukraine as Kyiv's highly-anticipated counteroffensive fails to yield a breakthrough and the world's attention pivots to the Israel-Hamas war.
In the US, Senate Republicans are blocking additional Ukraine funding in a row with Democrats over US border security whereas in the EU, negotiations on a 50-billion-euro package ($53 billion) for Ukraine over the next four years are dragging on.
The Kiel Institute figures showed newly committed aid between August and October 2023 came to just €2.11 billion, an 87% drop year-on-year.
Of 42 donor countries tracked by the study, only 20 had committed new aid packages to Ukraine in the last three months, the smallest share since the start of the war.
"Given the uncertainty over further US aid, Ukraine can only hope for the EU to finally pass its long-announced EUR 50 billion support package," it said, adding that any further delay would "clearly strengthen" Russia's hand.
Meanwhile, one person was killed and grain infrastructure damaged by a Russian drone attack near the Danube River, the governor of Odesa region said.
The governor said the drones attacked over two hours overnight, and that while most were shot down, some got through, damaging a storage building, a lift and trucks.
Ukraine's Danube ports have become a key artery for the country's huge export volumes of grain as Russia blockades the Black Sea since invading its neighbour in February 2022.
Moscow hit Danube port infrastructure with waves of drone attacks in August and September, but the latest overnight attack came after a lull in such strikes.
Ukraine's air force said 18 Shaheds were launched in total at the southern Odesa region and Khmelnytskyi region, which is in west Ukraine.
Fifteen of the drones were shot down by air defence rocket systems and mobile fire groups, the air force said.
