Russia continued its attacks on Kyiv for another consecutive night as air defenses in Ukraine's capital shot down Russian drones into Sept. 1, according to Kyiv Independent journalists on the ground.

Koretskyi said the move was necessary as the defense against Russia's full-scale invasion is becoming significantly more expensive.

A Ukrainian drone attack damaged the Russian Baltic Sea port of Ust-Luga in Leningrad Oblast early on Sept. 1, regional Governor Alexander Drozdenko said.

One drone crossed into southeastern Estonia, while another flew toward the border city of Narva but changed course before entering the country’s airspace, Estonian Air Force Commander Brigadier General Riivo Valge told public broadcaster ERR.

The heaviest toll was reported in Kyiv and the surrounding oblast, where Russia’s fifth consecutive day of attacks killed at least 12 people and injured 21 others.
