Ukraine war: 'Biggest' offensive blow awaits Russia, night attacks, Navalny anti-war campaign

"Massive" Russian attacks targeted Kyiv and other Ukrainian cities of Lviv and Zaporizhia overnight from Monday to Tuesday, according to authorities.

Explosive drones attacked Ukraine's capital in waves from multiple directions, wrote the city's military administration on Telegram, adding the alert had lasted more than three hours. 

In the western city of Lviv, "critical infrastructure" was hit by drones, said the head of the regional administration, Maksym Kozytskyi. 

Meanwhile, authorities in Zaporizhia said the city had been subjected to a "massive attack" aimed at civilian objectives, including residential suburbs. 

The Ukrainian General Staff later claimed the country's air defences shot down 28 out of 30 drones launched by Russian forces overnight. 

No casualties were immediately reported. 

Navalny urges anti-war campaign

Alexei Navalny urged his supporters on Monday to begin a broad campaign against Moscow's actions in Ukraine. 

The imprisoned Russian opposition leader made the remarks as he went on trial on new charges of extremism that could keep him behind bars for decades.

Navalny said the anti-war effort must reach out to millions and explain the disastrous impact of the fighting and “combat Putin's lies and the Kremlin's hypocrisy.” 

He argued that despite a relentless crackdown on dissent, such a campaign could be efficiently conducted on messaging apps outside the authorities' control.

“No one but us could enter this fight for our citizens' hearts and minds, so we need to do it and win,” Navalny said.

Soon after it started, the judge closed the trial despite his demand to keep it open.

In a statement posted on social media by his allies, Navalny declared the decision to close the trial was a sign of fear by President
