Ukrainian drones hit a Russian oil facility some 1,500 kilometers from the Ukrainian border, officials said, the latest in the series of long-range strikes targeting Russian energy facilities.
The April 30 attack came hours after US President Donald Trump and his Russian counterpart, Vladimir Putin, spoke by phone to discuss a potential cease-fire aimed at pausing Russia's 4-year-old, all-out war on Ukraine.
Russian and Ukrainian Telegram channels, citing local residents, reported explosions overnight near an oil pipeline facility in Perm, with videos showing columns of flames and plumes of smoke billowing over the city.
Regional Governor Dmitry Makhonin said no injuries were reported.
Ukraine's lead security agency, meanwhile, claimed responsibility, saying it had targeted a major oil refinery in the city, a day after a similar attack on another facility near Perm.
"The enemy must understand a simple fact: it no longer has a 'safe rear'," the Security Service of Ukraine said in its statement on Telegram.
"Distance no longer guarantees protection -- every region where enterprises support the war against Ukraine is within reach," it added.
Ukraine has stepped up drone attacks on Russian energy facilities in recent months, curtailing exports and hampering Moscow's capacity to take advantage of a spike in global energy prices prompted by the Iran war and Tehran's effective closure of the Strait of Hormuz.
Ukrainian President Volodymyr Zelenskyy said Kyiv's forces would continue expanding the range of its strikes inside Russia.
"We will continue to extend these ranges, and these are entirely justified Ukrainian responses to Russian terror," he wrote in a post on X.
On April 28, a Ukrainian drone attack hit a Russian oil refinery in the Black Sea port of Tuapse, the third attack on the facility in less than two weeks, sending acrid smoke wafting over the region.
Leaking oil was seen washing up on the coastal beaches, as workers struggled to clean up shorelines.
Russia, meanwhile, hit the Ukrainian Black Sea port city of Odesa overnight, and Ukrainian officials reported that at least 20 people were injured, three of them critically condition.
The attack caused widespread damage, including residential buildings, a kindergarten, a hotel, a shopping center, and infrastructure facilities, the regional governor said.
Speaking to RFE/RL in the aftermath of the attack, Odesa resident Olena said her apartment was completely destroyed in the attack. "It is very difficult…. I don't have anything else," she said, standing in front of burnt walls.
A separate Russian attack on the eastern Ukrainian city of Dnipro killed one person and injured 15 others. The strike destroyed a bus and two cars.
According to the Ukrainian military, Russian forces launched one Iskander-M ballistic missile and 206 drones overnight.
Trump, Putin Discuss Temporary Cease-Fire
Trump and Putin held a phone call in which the two discussed a possible temporary cease-fire to halt fighting in the war in Ukraine.
Trump told reporters at the White House on April 29 that during the 90-minute conversation with Putin, a cease-fire next month to mark the anniversary of the end of World War II in Europe was broached.
Trump said he suggested "a little bit" of a cease-fire "and I think he [Putin] might do that."
Putin's foreign policy adviser, Yury Ushakov, told Russian media further details of the phone call, saying Putin said he was prepared to have a cease-fire through or around May 9, when Russia marks the defeat of Nazi Germany.
Ushakov noted that the phone call was initiated by the Russian side.
The comments come after Russia's Defense Ministry said the annual Victory Day parade on Red Square -- a Kremlin spectacle celebrating the Soviet role in World War II and Moscow's military today -- would be drastically scaled back this year, with no military vehicles or heavy weaponry on display for the first time in almost two decades.
Zelenskyy, in reaction to the Trump-Putin call, said that he had instructed his team to contact US administration to clarify Russia's proposed temporary cease-fire.
"We will clarify what exactly this is about -- a few hours of security for a parade in Moscow, or something more," Zelenskyy wrote on X.
