Russian forces struck a train platform at Dnipro railway station on the morning of Oct. 29, killing at least 15 people and wounding at least 14 more, authorities said.

A passenger train was preparing to depart the platform for Zaporizhzhia when the station was attacked by a Russian jet-powered drone, Ukrainian Railways wrote on social media.

The brazen daytime attack was followed in close succession by deadly strikes against civilians in Chernihiv and Kremenchuk.

The strikes on civilians come not only in the middle of a scheduled local ceasefire in Kherson Oblast, agreed to by Kyiv and Moscow to help evacuate and deliver aid to the residents of the occupied city of Oleshky, but also ahead of the first trilateral "peace negotiations" mediated by the United States since February this year.

According to Ukraine's Air Force, Dnipro was attacked around 11:00 a.m. by four Russian jet-powered drones, three of which were downed by Ukrainian air defense before reaching their targets.

Despite the air raid alert and announcements of a heightened threat, people remained on the platform, Ukrainian Railways said.

Passengers were told to evacuate from the stationary train around ten minutes before the strike, with station and train staff checking each train car one by one.

At 11:29 a.m., Dnipropetrovsk Oblast governor Oleksandr Hanzha reported that medics were already at the scene of the attack, providing first aid.

"A horrific Russian attack on Dnipro train station," President Volodymyr Zelensky wrote on social media in response to the attack. "The Russians used a drone to attack a platform where a regular commuter train and a regular passenger train were standing."

"How many such terrorist attacks has Russia carried out on our people after lifting sanctions on some Russian oligarchs and energy companies instead of de-escalating."

Throughout the day, international leaders reacted, condemning Russia's attacks especially at a time of claimed progress in the peace process.

"We must aspire to far more than a localized ceasefire like the one that has just been negotiated locally in Oleshky," French President Emmanuel Macron wrote.

"It is intolerable that Russia continues to oppose all proposals to this end, continuing to bet on escalation and targeting civilians."

Latvian Foreign Minister Baiba Braze described the attack on Dnipro as "mass murder."

"Conducting these State sponsored terrorist attacks does not signal readiness for peace," she wrote on social media.

At around 7 a.m. local time on Oct. 30, Hanzha reported that a 40-year-old man had died in hospital from his severe injuries, bringing the death toll from the Russian attack to 15 — 10 men and five women.

As of the morning of Oct. 30, 11 people remained hospitalized, six of them in serious condition, including an 11-year-old boy.

Following the Oct. 29 Russian attack on Dnipro, 25,000 people in the city and surrounding Oblast were left without electricity, Hanzha said in the afternoon.

Dnipro Mayor Borys Filatov reported on Oct. 29 that a Russian drone struck the dormitory of a vocational school in Dnipro, setting the entire fifth floor on fire. There were no injuries, Filatov said, as the students had managed to reach the shelter before the strike.

Throughout the day, Russian attacks across Dnipropetrovsk Oblast injured four more people, including a 15-year-old girl, Hanzha said in an evening statement on Oct. 29.

The attack on Dnipro is just the latest in Russia's escalating campaign to strike Ukraine's railway infrastructure, including the targeting of passenger trains themselves.

Russia's recent targeting of Ukrainian Railways facilities — facilitated by the use of jet-powered drones — has led to strict new rules in the event of air raid alerts, with passengers often evacuated in the middle of the countryside for hours until the all-clear is sounded.

The threat warnings also affect trains waiting at stations, where passengers are likewise told to exit the trains, though the accumulation of people waiting for their train to leave and the reluctance of some to go to a shelter often creates new safety risks.

Elsewhere across Ukraine, the cities of Chernihiv and Kremenchuk were also targeted by daytime Russian attacks.

Around noon, Russian forces struck the center of Chernihiv in northern Ukraine with Banderol cruise missiles, killing two 15-year-old girls, regional governor Viacheslav Chaus said.

At least 25 more people were injured in the attack, including four children, the youngest one 10-months-old, Chaus later said.

Meanwhile, in the city of Kremenchuk in Poltava Oblast, at least three people were killed and 32 injured, including six children and two people still in critical condition, after Russian drones struck an apartment building in a residential area, according to local authorities. Oct. 30 has been declared a day of mourning in Poltava Oblast.
