Seven people are dead and more than a dozen others were injured after a man opened fire on civilians in a street in Kyiv on Saturday before taking hostages in a supermarket, Ukrainian authorities said.

KYIV, Ukraine (AP) — Russian strikes killed at least two people in Ukraine, officials said Sunday, as Ukraine's military struck a drone factory in southwestern Russia. A “massive” nighttime drone strike on Chernihiv in northern Ukraine killed a 16-year-old boy and wounded four others, according to the head of the city's military administration.

Nearly 700 drones and 19 missiles struck cities across the country overnight, killing 16 people, officials said. Ukraine's capital, Kyiv, was among the hardest hit.

Ukraine’s military is increasingly using robots to replace human soldiers, even in combat assault missions, helping to counter Russia’s manpower advantage.

Patriot missiles are in increasingly short supply amid extensive deployment in the Gulf against Iranian attacks. And Europe's only anti-ballistic system, the Italo-French SAMP/T, ​is produced in relatively small numbers.

Russia's FSB accuses the woman, found with a bomb in her backpack, of taking part in a plot hatched by Ukraine.

Ukraine attacked two Russian refineries and other key oil targets overnight into Saturday, officials said, just hours after the United States granted Moscow another waiver on the sale of its sanctioned oil.

It’s opening the door to a nightmarish new type of conflict in which machines hunt down and exterminate humans — changing war everywhere.
