KYIV, Ukraine (AP) — At least 13 people were killed Sunday by shelling at a market on the outskirts of the city of Donetsk in Russian-occupied Ukraine, local officials reported Sunday.

A further 10 people were injured in the strike on the suburb of Tekstilshchik, said Denis Pushilin, head of the Russian-installed authorities in Donetsk. He said that the shells had been fired by the Ukrainian military.

Kyiv has not commented on the event and the claims could not be independently verified by The Associated Press.

Emergency services continue to work on the scene, Pushilin said.

Also Sunday, fire broke out at a chemical transport terminal at Russia’s Ust-Luga port following two explosions, regional officials said. Local media reported that the port had been attacked by Ukrainian drones, causing a gas tank to explode.

The blaze was at a site run by Russia’s second-largest natural gas producer, Novatek, 165 kilometers southwest of St. Petersburg.

The head of the port in Russia’s Kingisepp region, Yuriy Zapalatskiy, said in a statement that there were no casualties, but that the district had been placed on high alert.

News outlet Fontanka reported that two drones had been detected flying towards St Petersburg Sunday morning, but that they were redirected towards the Kingisepp region. The Associated Press could not independently verify the reports.

The Russian Ministry of Defense did not report any drone activity in the Kingisepp area in its daily briefing. It said that four Ukrainian drones had been downed in Russia’s Smolensk region, and that two more had been shot down in the Oryol and Tula regions.

Russian officials previously confirmed that a Ukrainian drone had been downed on the outskirts of St. Petersburg on Thursday.
