CHERNIHIV: Seven people including a 6-year-old child were killed and at least 90 wounded when a Russian missile struck a central square in the historic northern Ukrainian city of Chernihiv, the interior ministry said on Saturday.

People had been on their way to church to celebrate a religious holiday when the strike took place, the ministry said, adding 12 of the wounded were children and 10 were police officers.

“A Russian missile hit right in the centre of the city, in our Chernihiv. A square, the polytechnic university, a theatre,” President Volodymyr Zelenskiy, who was on a working visit to Sweden, posted on Telegram.

“An ordinary Saturday, which Russia turned into a day of pain and loss,” he added.

A short video accompanying Zelenskiy’s post showed debris scattered across a square in front of the regional drama theatre, where parked cars were heavily damaged. The video also briefly showed a body slumped inside a car.

Ukrainian media reported that a public event featuring drone manufacturers had been taking place inside the theatre at the time of the attack. Both sides in Russia’s 18-month-old invasion have widely used drones on the battlefield.

In comments to reporters, Interior Minister Ihor Klymenko confirmed only that an unspecified event had been taking place in the building and that Ukraine’s domestic security service was investigating the matter.

Chernihiv is a city of leafy boulevards and centuries-old churches about 145 km (90 miles) north of the capital Kyiv.

The roof of the neoclassical theatre was torn off by the strike, which also blew out doors and windows in neighbouring apartment buildings and store fronts.

The streets were stained with blood trails and strewn with scraps from first-aid supplies that had been used to treat the wounded.

Russia has attacked Ukrainian cities far from the frontline with missiles and drones as part of the full-scale invasion it launched in February last year.
