KYIV: Nighttime Ukrainian strikes disrupted power and heating to two major Russian cities near the Ukrainian border, local Russian officials reported Sunday.

The report comes as Russia and Ukraine have traded almost daily assaults on each other's energy infrastructure and US-led diplomatic efforts to stop the nearly four-year war have not advanced.

A drone strike temporarily caused blackouts and cut heating to parts of Voronezh, regional Gov Alexander Gusev said. He said several drones were electronically jammed during the night over the city, home to just over 1 million people, sparking a fire at a local utility facility that was quickly extinguished.

Russian and Ukrainian news channels on Telegram claimed the strike targeted a local thermal power plant.
