Twin sisters have been named among 10 people killed in a missile strike on a popular pizza eatery in Ukraine, as authorities arrested a man suspected of helping the Russians with the attack.

Police said at least 61 people were wounded in the bombing on Tuesday night (local time) in the city of Kramatorsk as diners were crowded into the Ria Pizza restaurant.

The venue is popular with young people, aid workers and journalists.

Ukraine’s Security Service said a man was suspected of filming the restaurant for the Russians and informing them of its popularity, the ABC reports.

The detained suspect was an employee of a gas transportation company. No evidence has been provided to back up the claim.

As Russia remained adamant it did not targe civilians, rescuers were pulling bodies and injured survivors from the rubble, including a baby.

Tears were shed for twins Yulia and Anna Aksenchenko, 14, who were killed.

The city’s Education Department said the girls would have turned 15 in September.

“Russian missiles stopped the beating of the hearts of two angels,” it said in a Telegram post.

The restaurant building was reduced to a twisted web of metal beams.

“I ran here after the explosion because I rented a cafe here …Everything has been blown out there,” said Valentyna, a 64-year-old woman who declined to give her surname.

“None of the glass, windows or doors are left.

“All I see is destruction, fear and horror.

“This is the 21st century.”

A second missile hit a village on the fringes of Kramatorsk, wounding five.

President Volodymyr Zelensky said in his nightly video message on Tuesday (local time) the attacks showed Russia “deserved only one thing as a consequence of what it has done — defeat and a tribunal”.

Russia has frequently hit Ukrainian cities since its full-scale invasion in February 2022 but denies targeting civilians.

Kramatorsk lies west of the front lines in Donetsk province and is a likely objective in any westward advance by Russia.

The city has been a frequent target of Russian attacks, and a missile strike killed 63 people at a railway station in April 2022.

Earlier, Ukraine’s government reprimanded Kyiv mayor Vitali Klitschko after criticism of city officials over the state of bomb shelters following the deaths of three people locked out on the street during a Russian air raid.

The government said it had also approved the dismissal of the heads of two Kyiv districts and two acting heads of districts.

Uncertainty about the Kyiv mayor’s political future grew after Mr Zelensky criticised officials in the capital over the June 1 incident, in which two women and a girl were killed by falling debris after rushing to a shelter and finding it shut.

Mr Zelensky also ordered an audit of all bomb shelters in Kyiv after the incident, and said personnel changes would be made.

Prime Minister Denys Shmyhal told a government meeting the audit ordered by Mr Zelensky had found 77 per cent of the shelters in Ukraine were fit for use, but many did not “meet any standards”.

He said the situation was “unacceptable” in some places, and mentioned districts in the Zaporizhzhia, Sumy, Zhytomyr and Kyiv regions as well as the city of Kyiv.
