The alarms blared in the capital, Kyiv, as well as in the Chernihiv, Cherkasy, Poltava, Kharkiv, Dnipropetrovsk, Mykolayiv, and Zaporizhzhya, and Odesa regions.
A series of blasts was reported in the Kharkiv region, although information on possible casualties or damages was initially unavailable.
The Ukrainian General Staff said on September 16 that its forces were conducting defensive operations in eastern and southern Ukraine and offensive operations around Melitopol and Bakhmut.

Ukrainian Digital Transformation Minister Mykhaylo Fedorov, who has participated in building up his country's advanced fighting abilities, warned Moscow's military that following recent attacks on Russian naval targets in the Black Sea, "There will be more drones, more attacks, and fewer Russian ships.

Governor Roman Starovoit of Russia's Kursk region said on Telegram on September 16 that Ukrainian forces shelled a village in Russia's Kursk region, killing a 30-year-old civilian.

"The enemy did not abandon plans to capture the city of Artyomovsk of the Donetsk People's Republic and continued to conduct assault operations...unsuccessfully trying to oust Russian troops from the population centers of Klishchiyivka and Andriyivka," the Russian ministry said in its daily briefing, according to Reuters.
RFE/RL can't independently confirm battlefield claims by either side in areas of the heaviest fighting in Ukraine, and censorship and strictures on the media seriously hinder reporting in Russia.
Reports have suggested that pressure from the United States and other allies has mounted on Ukraine to demonstrate success in the ongoing major counteroffensive it launched in June. Zelenskiy and other Ukrainian officials have pushed back on criticisms about the pace of the Ukrainian military's push to retake Russian-occupied areas of southern and eastern Ukraine.

"This week, we’ve made significant progress in implementing existing defense agreements and other support packages," Zelenskiy said.

"Germany, thank you for the new batch of military aid. Belgium, your participation in our pilot training is approved. Thank you! Norway, your decision to provide additional funding for Ukraine's recovery. It's crucial. Thank you!"
