LONDON—Russian gas supply to Europe via the Nord Stream 1 pipeline fell further on Thursday and Moscow said more delays in repairs could lead to suspending all flows, putting a brake on Europe’s race to refill its gas inventories.
The faltering flows came as the leaders of Germany, Italy, and France visited Ukraine, which is pressing for swifter weapons deliveries to battle invading Russian forces and wants support for Kyiv’s bid to join the European Union.
