Russia unleashed new air strikes on Ukraine early on Friday, killing a 10-year-old boy in the northeastern city of Kharkiv and damaging grain and port infrastructure in the Odesa region in the south, Ukrainian officials said.

The boy was killed when Russia hit Ukraine’s second-biggest city with two Iskander ballistic missiles, regional governor Oleh Synehubov said. Twenty-three others were wounded, including an 11-month-old baby, he said.

The boy’s father, Oleh Bychko, told Reuters he had managed to pull his younger son and wife out of the rubble after the strike. Bychko, his face scratched and his clothes covered in blood, stood shocked and lost for words after the death of his 10-year-old son, Tymofiy.

The missile attack destroyed much of a residential building. The attacks followed a Russian missile strike on Thursday in which Ukrainian officials said dozens were killed in a village in Ukraine during a gathering to mourn a fallen Ukrainian soldier.
