Russia has accused Ukraine over explosions which reportedly killed three people in the city of Belgorod, near the border with Ukraine.
The regional governor said the blasts hit dozens of residential buildings and air defences had been activated.
The Kremlin said that Sunday’s attack had been a deliberate attempt by Ukrainian forces to target civilians.
Ukraine dismissed the claim, saying the Russians had lied about similar incidents in the past.
Belgorod – a city of 370,000 that lies just north of Ukraine’s second city, Kharkiv – has been attacked on several occasions since Moscow invaded Ukraine in February.
The latest incident happened in the early hours of Sunday morning. Russian defence ministry spokesman Igor Konashenkov said air defences had destroyed three Ukrainian Tochka-U ballistic missiles with cluster warheads, but fragments of one of them fell on a block of flats.
“This missile attack was intentionally planned and launched at the civilian population,” he added.
