A 14-year-old girl was killed in a Russian attack on Kharkiv, Ukrainian officials have said.
At least six people were killed in all, as a 12-storey building was hit alongside a playground, in the industrial district.
The Russian-guided bomb attack in the northeastern city also left 55 people injured.
About 20 of the injured were in severe condition, regional governor Oleh Syniehubov said.
“Occupiers killed a child right on the playground,” Ihor Terekhov, the city’s mayor, said on Telegram.
Ukraine’s second-largest city has long been a target for Russia, ever since its full-scale invasion in February 2022.

Video from the site of the Kharkiv attack, shared by Mr Zelenskyy’s chief of staff, showed huge flames and black smoke rising from the upper floors of the building.
In light of the attack, the Ukrainian president renewed his calls to Western allies to allow him to use their weapons in long-range attacks on Russia.
“A strike … would not have happened if our defence forces had the ability to destroy Russian military aircraft where they are based. We need strong decisions from our partners to stop this terror,” Mr Zelenskyy said.
Ukrainian authorities said Friday’s attack involved five aerial-guided bombs launched from planes in Russia’s Belgorod region.
The US ambassador to Ukraine described the Kharkiv attack as a “war crime” and called for Russia to be held accountable.

Ukrainian F-16 pilot ‘killed by friendly fire’
A Ukrainian F-16 pilot was killed by friendly fire, an MP has claimed.
The commander of Ukraine’s air force criticised the comments, made by Ukrainian MP Mariana Bezuhla, and US experts have joined the investigation to try and find out what happened.
Lieutenant Colonel Oleksiy Mes was killed while defending Ukraine’s skies from a huge Russian aerial attack at the start of the week.

Ms Bezuhla claimed his jet was shot down by a US-supplied Patriot missile.
In response, air force commander Mykola Oleschuk said her words were a “tool to discredit the top military leadership”.
But, the air force did not directly deny that the F-16 was hit by a Patriot missile.
