A Ukrainian drone attack on Russia’s Black Sea port of Tuapse sparked a fire and killed at least one person, Russian officials said on Monday, ​only hours after a blaze was extinguished following a similar ​attack on April 16.

One of Russia’s major southern ports, Tuapse, ⁠is an oil product export hub that also handles dry bulk ​cargo, such as coal and fertiliser.

In addition, it is home ​to a major oil refinery of the same name owned by Rosneft.

“Tuapse was subjected to another massive drone attack,” Veniamin Kondratiev, governor of the Krasnodar region, said ​on messaging app Telegram. “A fire occurred at the seaport.”

Kondratiev said one ​man was killed at the port and another injured, while debris from drones ‌damaged ⁠several city buildings, ranging from a kindergarten and primary school to a church and residential apartment block.

Ukraine has intensified attacks on Russia’s energy infrastructure in the past month as US-brokered peace talks have stalled, with ​Washington more focused ​on the war ⁠in Iran.

Tuapse’s local prosecutor’s office said transport infrastructure was damaged at the port, while RIA Novosti news ​agency said state-controlled schools cancelled lessons on Monday.

Russia’s defence ​ministry said ⁠112 Ukrainian drones were destroyed over the country overnight.

Tuapse’s port terminals export naphtha, fuel oil, vacuum gasoil and high-sulphur diesel produced by the ⁠local refinery ​as well as oil processing plants in ​the Samara region and Rosneft’s Saratov refinery on the shore of the river Volga.
