In a frontline city, parents don’t see schools built below ground as apocalyptic. Instead, they offer relief from worry about the threat of Russian strikes.

An attack by what Ukrainian officials said was a Russian drone with an Nvidia chip presages a dystopian future of weaponry untethered to humans.

The tech giant says it does not sell the devices in Russia, but they are widely available on resale markets. When purchased that way, they are virtually impossible to track.

The recently ousted Ukrainian defense minister, Mykhailo Fedorov, an advocate for drone and robot warfare, says Ukraine’s tech-heavy strategy will persist.

President Volodymyr Zelensky of Ukraine has pivoted from unpopular moves before, but a recent decision about military leadership and strategy could weaken his position.

With anger high over the firing of the defense minister, the president’s office is signaling an openness to compromise.

At a conference on reconstruction, the focus shifted to private investment, not donor assistance.

The popularity of drones, and the defense minister who heavily promoted them, helped lead to a clash in which President Volodymyr Zelensky sided with the military brass.

From an underground parking garage, Ukraine’s newly dismissed defense minister aired the most dramatic, public critique of the military command to emerge during the war.

Mr. Fedorov became the youthful face of Ukraine’s successful drone warfare program. The move to replace him has prompted street protests.

Demonstrators demanded the reinstatement of Mykhailo Fedorov, who had come to symbolize Ukraine’s success in using drones to strike back against Russia.

Mykhailo Fedorov announced he was leaving the ministry on Wednesday after conflicts with generals and military contractors over the role of innovative robot and drone weapons in war.

President Volodymyr Zelensky said Ukraine’s prime minister, Yuliia Svyrydenko, would step down amid a broader shake-up in Ukraine’s senior leadership.

“After 26 years in power, age is beginning to take its toll,” President Volodymyr Zelensky of Ukraine wrote of his Russian counterpart, bragging of a recent strike on St. Petersburg.
