Heraldo de Madrid - Russia hits Kyiv with deadly attack after vowing retaliation

Multiple rounds of loud explosions were heard in the Ukrainian capital throughout the early hours of the morning, according to AFP journalists.

"Tonight Kyiv region is once again enduring a mass enemy attack with strike drones, cruise missiles and ballistic missiles," said Mykola Kalashnyk, the head of the regional ministry administration.

The blasts caused a residential building near the government district to shake, while dozens of people took shelter in an underground metro station in the city centre, AFP reporters witnessed.

Residents were instructed to stay in shelters as city authorities warned fires had broken out and city military administration head Tymur Tkachenko said one person had been killed and at least 20 wounded.

Ukrainian authorities and the US embassy had earlier warned of a possible significant attack on Kyiv after Russia said it would "punish" those responsible for deadly strikes in a part of eastern Ukraine under its control.

"The capital has come under a mass ballistic missile attack," Tkachenko wrote on Telegram early on Sunday.

He later said the air raid alert had been lifted.

Mayor Vitali Klitschko said damage had been recorded in every district of Kyiv, adding that a strike on a school had sparked a fire, and another on a business centre had led to people being trapped in a shelter.

- Missile attack warning -

Ukraine had been expecting a major attack after its own forces launched a drone barrage in the Russian-occupied east of the country, which Moscow said hit a college dormitory and killed at least 18 people.

Launched overnight on Thursday to Friday, the drone salvo -- one of Ukraine's deadliest such strikes in months -- also wounded 42 in Starobilsk, in the occupied Lugansk region, trapping people beneath the debris.

Ukraine denied targeting civilians, saying it had hit a Russian drone unit stationed in the Starobilsk area.

Russia's foreign ministry said on Friday that those responsible would face "inevitable and severe punishment".

On Saturday, President Volodymyr Zelensky warned that Ukraine was "seeing signs of preparation for a combined strike on Ukrainian territory, including Kyiv".

He said on social media that Moscow may deploy "various types of weaponry" including the nuclear-capable Oreshnik hypersonic missile. There were no initial reports that an Oreshnik had been used.

Similarly, the US embassy said it had "received information concerning a potentially significant air attack that may occur at any time over the next 24 hours".

Ukraine regularly targets Russian-controlled areas of the country with drones, saying the strikes are retaliation for Russian attacks.

- Dormitory death toll -

Russia's emergency ministry said on Saturday it had pulled two more bodies from the rubble of the dormitory, taking the death toll to 18.

Video shared by the ministry showed dozens of rescuers sifting through what remained of a section of the five-storey building.

Most of those killed and missing were young women born between 2003 and 2008, according to a list of casualties published by the Moscow-backed governor of occupied Lugansk, Leonid Pasechnik.

"The region and the entire country share the fate of these people and the pain of their families," he said on Telegram.

The United Nations said on Friday it "strongly condemns any attacks against civilians and civilian infrastructure, wherever they occur", adding it could not verify details due to restricted access to the area.

Starobilsk lies about 65 kilometres (40 miles) from the front line in eastern Ukraine. It was captured by Russian forces in the early months of the offensive in 2022.

Kyiv has recently expanded its drone capabilities and stepped up strikes on undisputed Russian territory, including residential areas and oil export infrastructure.

Moscow has launched mass barrages of missiles and drones at Ukraine almost daily since the full-scale offensive began in 2022, also hitting infrastructure and causing civilian deaths. It denies targeting civilians.

US-led efforts to negotiate an end to more than four years of war have slowed in recent months with Washington's attention diverted towards its conflict in the Middle East.
