The Delta system pulls together battlefield data to identify targets, creating a miles-wide “kill zone.” The technology is credited with helping to cut Russian advances to a near standstill.

Kyiv says the attacks are aimed at disrupting Russian supply chains and inflicting further pressure on Putin's wartime economy.

The lack of visible senior Trump administration participation was the latest sign of how Washington has backed off during a critical juncture for Ukraine.

Former senior Russian diplomat says U.K. factories making drones for Ukraine "could be attacked - not by Russia, but from unknown sources."

MOSCOW, Aug 25 (Reuters) - A senior Vatican official urged an end to the Ukraine war after meeting in Moscow on Tuesday with Russian Foreign Minister Sergey Lavrov in the first in-person talks between Vatican and Russian officials in five years.

Ukraine pleaded for the expensive weapons, and ultimately got them, but drones have rendered them almost unusable.

European leaders joined President Volodymyr Zelenskyy in Kyiv on Monday for official celebrations marking Ukraine's Independence Day as Russia pushes on with its invasion of the country.

Polish President Karol Nawrocki wished Ukraine victory in its war against Russia in an Independence Day letter to Volodymyr Zelenskyy, while noting tensions in Polish-Ukrainian relations.
