Russia says Ukraine launched a major drone attack after Moscow shunned ceasefire offer

Russian air defenses shot down 347 Ukrainian drones overnight, Russia's Defense Ministry said Thursday, in what appeared to be a major attack after Moscow spurned Kyiv's ceasefire earlier in the week and tension mounted over safety at Russia's upcoming Victory Day celebrations.

Incoming drones were destroyed over 20 Russian regions, including Moscow, according to the Defense Ministry, in Ukraine's second-biggest aerial attack since Russia's all-out invasion more than four years ago. The largest was in March when it launched 389 drones.

Dozens more Ukrainian drones were launched during daylight hours Thursday, the ministry said, including some heading again toward Moscow. Nearly 100 flights in and out of the Russian capital's three main airports - Sheremetyevo, Domodedovo and Vnukovo - were delayed or canceled by midday, the Moskva news agency reported.

The attacks came ahead of Russia's most important secular holiday, Victory Day, which marks the anniversary of the defeat of Nazi Germany in World War II. Russian authorities have declared a unilateral ceasefire in Ukraine for Friday and Saturday.

Ukraine had responded to that with its own suspension of hostilities from midnight Tuesday. But Ukrainian President Volodymyr Zelenskyy said Moscow disregarded the goodwill gesture and launched fresh attacks.

"Russia has not stopped any type of its military activity. Unfortunately, it has not stopped. Ukraine will act symmetrically," Zelenskyy said in his regular evening video address Wednesday.

He said Thursday on X that Russia's attacks have been ceaseless, with drones, missiles, artillery shelling and glide bombs hitting civilian areas of Ukraine, including the power grid and rail network.

In the northeastern city of Kharkiv, Ukraine's second-largest, a drone strike wounded nine people, including three children, local officials said.

Tension has grown as Russia's Victory Day celebrations approach and U.S.-led peace efforts gain no traction. Rustem Umerov, the head of Ukraine's National Security and Defense Council, was in the United States on Thursday and preparing to meet with Trump administration representatives, according to Zelenskyy.

All mobile internet access and text messaging services will be shut down in the Russian capital on May 9, state media reported Thursday, citing the country's Ministry of Digital Development, Communications and Mass Media.

A traditional parade in Moscow won't feature the usual tanks, missiles and other military equipment for the first time in nearly two decades.

The Russian Defense Ministry cited the "current operational situation" as a reason for excluding military equipment.

Russian authorities say they are concerned about possible Ukrainian attacks, as Kyiv has expanded its long-range drone and missile capabilities.

Kremlin spokesman Dmitry Peskov said Thursday that additional security measures were being taken due to the "rather complex operational situation."

The measures being taken "are necessary to ensure the safety of citizens, which is an absolute priority," Peskov told reporters.

Among the foreign dignitaries expected to attend the Victory Day ceremonies on Saturday are Malaysia's King Sultan Ibrahim Iskandar, Laos President Thongloun Sisoulith, and Belarus' authoritarian leader Alexander Lukashenko. Slovakia's Prime Minister Robert Fico was to meet with Putin and lay flowers at the tomb of the unknown soldier but stay away from the parade.

Russia repeated its recent warnings to Ukraine that it would take decisive action - including a potential mass strike on Kyiv - if Ukrainian attacks disrupt the occasion.

"We have strengthened our focus on the possibility of retaliatory measures," presidential aide Yuri Ushakov told journalists Thursday.

Also, Russia's Foreign Ministry advised foreign embassies and international organizations located in Kyiv to evacuate their offices in case such a strike did take place.

Ukraine's air defense shot down 92 of the 102 drones Russia launched overnight, the military said.

Russia maintains a significant advantage in drone numbers, regularly deploying hundreds in a single attack.
