Ukrainian officials reported more strikes on Tuesday, including one on the southeastern town of Zaporizhzhia that killed at least one person, a day after Russia's missile strikes on Kyiv and other regions. 

The State Emergency Service of Ukraine said 19 people died and 105 people were wounded in Monday's missile strikes. Around 300 settlements in the regions of Kyiv, Lviv, Sumy, Ternopil and Khmelnytsky remained without electricity on Tuesday morning, according to Ukrainian First Deputy Interior Minister Yevhen Yenin.

Ukrainian President Volodymyr Zelenskyy is expected to attend an emergency G7 meeting on Tuesday to push the case for more military assistance, especially for more air defense systems in light of this week's missile and drone strikes, BBC reported.

More strikes

The Lviv region in western Ukraine on Tuesday was hit by strikes that targeted the region's energy facilities and left part of Lviv city without power, mayor Andriy Sadovyi said on Telegram.

The Russian Defense Ministry confirmed the attacks, saying it had carried out massive strikes using long-range and high-precision weapons and that "all assigned targets were hit."

Vitaliy Kim, the governor of Ukraine's southern town of Mykolayiv, said Russia seemed to have changed tactics. 

"They launch rockets more than once so that our people can wait and our air defense can work, but at intervals they launch significantly fewer rockets and keep people in shelters. What is this if not terror?" he said on national television. 

Last week, the Russian Defense Ministry named Air Force General Sergei Surovikin as the overall commander of the military operation in Ukraine. 

Open to talk with the West

Russian Foreign Minister Sergei Lavrov said on Tuesday that Moscow was open to talks with the West on the Ukraine conflict but had yet to receive any serious proposal to negotiate. 

In an interview on state TV, Lavrov said Russia is willing to engage with the U.S. or with Türkiye on ways to end the conflict. 

Russian President Vladimir Putin will meet Turkish President Recep Tayyip Erdogan in Astana on Thursday to discuss Ukraine and bilateral relations, the Kremlin said on Tuesday. 

Zelenskyy vowed that Ukraine would keep fighting in a video address on Monday night. "We will do everything to strengthen our armed forces. We will make the battlefield more painful for the enemy."
