Intense Russian drone and missile strikes on cities in Ukraine have left at least six people dead, including two children, President Volodymyr Zelensky has reported.

Another 21 individuals were injured during the attacks, reinforcing the notion that Moscow has not faced sufficient pressure regarding its continuation of the war.

Earlier, US President Donald Trump postponed an anticipated summit with Russia's Vladimir Putin, stating he wished to avoid a wasted meeting.

The Kremlin has dismissed calls for a ceasefire, despite appeals from Trump and European leaders.

In retaliation, Ukraine's military launched an attack on a Russian chemical plant in the Bryansk border region using UK-supplied Storm Shadow missiles, describing it as a successful hit.

Strikes resulted in fatalities across various locations, including a couple in their 60s and a six-month-old baby. The Ukrainian capital was under ballistic missile warnings and explosion sounds echoed throughout the night, with emergency services battling fires in residential areas. Additionally, attacks targeted energy infrastructure, leading to power outages.
