Europe must have its own defence system against ballistic missiles and Ukraine is holding talks with several countries to create one, Volodymyr Zelenskyy said on Sunday. Ukraine relies heavily on scant supplies of the Patriot system, produced by the US, to shoot down Russian missiles, which are often fired at Ukraine’s electricity generation and transmission systems. “I believe, and my idea is, that we should have a European anti-ballistic missile defence system. We are in talks with several countries and are working in this direction,” Zelenskyy told the national TV channel, Marathon. “We need to build our own anti-ballistic missile defence system within a year.”

Fire Point, maker of Ukraine’s Flamingo cruise missile, told Reuters this month that it was in talks with European companies to launch a new air defence system by next year, creating a low-cost alternative to the Patriot which is in increasingly short supply amid extensive deployment in the Gulf because of Donald Trump’s war against Iran. Europe’s only anti-ballistic system, the Italo-French SAMP/T, is produced in relatively small numbers.

A “massive” night-time drone strike on Chernihiv in northern Ukraine killed a 16-year-old boy and wounded four others, the head of the city’s military administration said on Sunday. Russian drones also attacked the southern city of Kherson on Sunday, local officials reported. A man died of his wounds after a drone hit a van driving through the city centre, according to Oleksandr Prokudin, the head of the regional administration. A second man was hospitalised with blast injuries, regional authorities said.

Ukraine hit the Atlant Aero drone factory in the city of Taganrog, the Ukrainian military general staff reported. The site lies about 55km (35 miles) east of Russian-occupied eastern Ukraine in south-western Russia. According to the military, the strike started a fire at the factory, which designs and produces strike and reconnaissance drones, as well as components for more powerful UAVs that can carry guided bombs weighing up to 250kg.

Ukraine’s navy said it carried out the Atlant Aero attack using domestically manufactured Neptune cruise missiles. Russian officials in Taganrog confirmed an attack on “commercial enterprises” as well as a vocational school and multiple cars.

Russia launched 236 drones into Ukrainian territory overnight into Sunday, Ukraine’s air force reported. Of those, 203 drones were shot down while 32 hit targets in 18 separate locations, it said. Russia’s defence ministry said its forces shot down 274 Ukrainian drones during the night, as well as guided aerial bombs and a Neptune cruise missile. The ministry did not say how many struck targets.

The centre-left coalition of Rumen Radev is expected to win Bulgaria’s parliamentary election, though without an outright majority, after polls closed on Sunday. Radev is seen by critics as pro-Russian and Eurosceptic. If he is able to form a government, this could pose another headache for the European Union in its support of Ukraine’s defence.

Though Radev has denounced the Russian invasion, he has opposed military aid to Ukraine and has favoured reopening talks with Russia as a way out of the conflict. It comes after Hungarian voters ousted Viktor Orbán, who cultivated close ties with the Russian president, Vladimir Putin, and obstructed European help for Ukraine.

Ukraine’s interior minister said on Sunday that two police officers had been suspended after a video circulated online showed them fleeing the scene of the shooting in Kyiv in which six people were killed. “Shameful, unworthy behaviour. This is a disgrace for the entire system. They have been suspended, and an investigation into this is underway,” said Igor Klymenko, the government minister. Zelenskyy, added that “there will be a full review of the patrol officers’ actions”.

Ukraine’s police chief, Ivan Vygivsky, told reporters that the suspect had served in the Ukrainian armed forces before retiring in 2005 and then lived in Russia until 2017. “We checked his social media pages … His views there are negative. You can’t say he had a pro-Ukrainian stance, it was, let’s say, somewhat in the other direction,” Vygivsky said.
