TERNOPIL, Ukraine (Reuters) -At least 26 people were killed and many were listed as missing in a Russian drone and missile attack overnight that hit apartment buildings in the western Ukrainian city of Ternopil, Ukraine's interior minister said on Wednesday.

Another 40 people were wounded in the overnight strikes on Ukraine that targeted energy and transport infrastructure, forcing emergency power cuts in a number of regions.

Closer to the frontline, schedules were changed and some trains cancelled as strikes have become more regular. In the northern border region of Sumy, the railway company announced on November 13 that it would reduce the number of trains departing from the town of Konotop while adding more carriages to the remaining trains.

Ukraine said it had successfully struck targets in Russia using U.S.-supplied ATACMS missiles, ending a months-long absence of the powerful weapon from the battlefield. In a statement shared on Facebook, the General Staff of the Armed Forces of Ukraine called it "an iconic event that emphasizes Ukraine's unwavering devotion to its sovereignty."

Ukrainian officials say a missile and drone attack killed dozens, right as the U.S. Army secretary arrived to push for peace talks.

It comes amid reports the US and Russia have prepared a 28-point peace plan, allegedly containing major concessions for Ukraine.

Ukraine said it had identified a Russian commander as a suspect in some of the killings in the Kyiv suburb of Bucha in 2022, calling it a vital step towards establishing the chain of command behind the mass executions of civilians there.
