Russia pummelled Ukrainian cities with missiles and drones overnight, killing at least 10 people and throwing doubt over Ukrainian President Volodymyr Zelensky’s attempts to “reinvigorate” the peace process with talks in Ankara later on Wednesday.

Zelensky touched down in Turkey on Wednesday morning for a trip that had seemed to raise the prospects of a revival in stalled diplomatic efforts to broker an end to Russia’s invasion.

But Moscow’s wave of overnight attacks was the latest in an intensifying campaign targeting Ukraine’s energy infrastructure and hitting a number of civilian sites as winter approaches.

The strikes hit two multi-storey residential blocks in the western city of Ternopil, Foreign Minister Andriy Sybiga said on social media.

Officials posted photos showing the shattered buildings, with massive fires visible through smashed-out windows.

Streets were covered with debris and parts of the city engulfed in thick grey smoke after explosions were reported at around 7.00am.
