Across eastern Ukraine, Russia’s tiny gains are adding up. It is capitalizing on a series of small advances and throwing significant resources into an emerging summer offensive, one that risks reshaping control over the front lines.

Ukraine faced another night of Russian drone assaults as several cities and regions came under attack between Tuesday night and early Wednesday morning, causing injuries and damage to both residential and critical infrastructure.

The move means Trump is walking back the 50-day deadline he set this month in response to Russia's continued bombing of Ukrainian cities.

The Kremlin said on Wednesday it continues to monitor statements by U.S. President Donald Trump regarding sanctions against Moscow, but that Russia had acquired immunity to such measures thanks to long experience.
