Russian drones have struck Ukrainian mobile carrier Kyivstar's headquarters in Kyiv over the weekend, as data centers in the country have also been targeted.

Kyivstar confirmed the attack to Interfax Ukraine news agency, reporting no injuries or casualties.

It's the third time this month that Kyivstar, Ukraine's largest mobile carrier, has been targeted by Russia.

The first time was on September 11, when a Russian drone attack struck a Kyivstar office in the capital. This was followed up by a second incident, when another Kyivstar building in Kyiv was attacked.

As previously reported by DCD back in 2023, the country's telecoms operators have faced ongoing challenges of rebuilding their respective mobile networks amid the country's ongoing war with Russia.

However, it hasn't just been Kyivstar that has seen its infrastructure attacked this week, as Vodafone Ukraine's also been targeted. Reuters reported that one of Vodafone's data centers was attacked over the weekend.

Vodafone hasn't publicly commented on the attack as of yet, though the company hasn't been the only one to see its data center infrastructure targeted.

Earlier this month, Russia claimed responsibility for an attack on the De Novo data center in Kyiv, Ukraine, one of the country’s largest data centers.

"Russia has targeted major Ukrainian ​data ⁠centers, seeking to disrupt the flow of information. Rapid alerts about missile and drone ⁠threats are ​essential - they save lives," ​said Andrii Sybiha, Ukraine's foreign minister, on X last week.

Ukrainian forces previously struck a Russian data center facility in Russian-occupied Prymorsk, in the Zaporizhzhia Oblast, Ukraine, earlier this year.

It was also reported last week that neighboring Poland has seen infrastructure attacked, including a fire at a Starlink satellite station. A Polish government minister labeled the fire as a deliberate "act of sabotage."

The fire in the Masovian Voivodeship province was "deliberately designed to disable the station... disrupting internet access for various institutions, including the Ukrainian army," said Krzysztof Gawkowski, Polish Deputy Prime Minister, per the BBC.
