Top Zelensky deputy resigns amid new flurry of Russian attacks on Ukraine

Driving the news: Kuleba didn't cite a reason for his resignation in a hand-written note shared by Ukrainian parliamentary Speaker Ruslan Stefanchuk in a Telegram post Wednesday.

• Lawmakers will discuss his letter at their next plenary session, Stefanchuk said.
• At least six other members of the Ukrainian government have also offered to resign, Stefanchuk wrote in a series of Facebook posts.

What they're saying: In his nightly address Tuesday, Zelensky stressed Ukraine's need to meet a list of priorities, including attracting investment for its defense industry, improving relations with NATO and strengthening ties between the central government and communities.

• "To do this, we need to strengthen some areas in the Government — and personnel decisions have been prepared," he said, while not directly addressing the specific cabinet departures.

The big picture: The leadership shakeup comes as Ukraine has weathered a series of devastating Russian attacks in recent days.

• On Tuesday, Russia launched one of its deadliest strikes on Ukraine since the start of the war, targeting a military academy and hospital in the city of Poltava in eastern Ukraine.
• The attack killed 51 people, according to Ukraine's Foreign Ministry. Zelensky said in his nightly address that the number of injured had risen to 271.
• Russia then targeted the city of Lviv, near the Ukrainian-Polish border, with aerial strikes on Wednesday.
• Maksym Kozytskyi, head of the Lviv regional administration, wrote on Telegram that the attack had killed at least seven people and injured 64 others.
