October is coming to an end and as winter approaches, many Ukrainians find themselves more vulnerable than ever in the face of mounting Russian air attacks. In Kyiv, Russian combined missile and drone attacks routinely result in mass casualty events.

Moscow Mayor Sergey Sobyanin said emergency services were working at the sites where debris fell. State propaganda agency RIA Novosti reported that Domodedovo and Zhukovsky airports had suspended flights.

Ukraine has ramped up its strikes on Russian military and energy targets far beyond the front lines in recent months.

In the city of Kherson, in southern Ukraine, small drones routinely target ordinary people by dropping hand grenades, and record video documenting their attacks, a U.N. commission reported.

Cartels and other criminal organizations in Mexico have increasingly used drones in attacks against rival groups or authorities.

Video from the Ukrainian military's first-person drones has captivated millions, but the footage offers only a narrow view of a robotics revolution that is reshaping combined-arms warfare.

President Donald Trump said two narco-terror suspects survived a U.S. military strike on a drug-carrying submarine, claiming it carried fentanyl and could have killed 25,000 Americans.

Western analysts say the attacks on energy infrastructure so far have had a serious — but not crippling — effect. Ukrainian drones have repeatedly hit 16 major Russian refineries, representing about 38% of the country’s nominal refining capacity, according to a recent review by the Carnegie Endowment, a U.S.-based think tank.
