KHARKIV, Ukraine (AP) — A Russian missile attack killed a 10-year-old boy and his grandmother Friday in the northeastern Ukrainian city of Kharkiv, officials said, a day after a strike in the same region killed at least 51 civilians in one of the deadliest attacks in the war in months.
Associated Press reporters saw emergency crews pulling the boy's body from the rubble of a building after the early morning attack. He was wearing pajamas with a Spider-Man design.
The strike also killed the boy's grandmother and injured an 11-month-old child, Interior Minister Ihor Klymenko said on Telegram.
Regional Gov. Oleh Syniehubov said 30 people were wounded and rescue operations were continuing.
Officials said preliminary information indicated the Kremlin's forces used two Iskander missiles in the attack, the same as in the previous day's attack on the eastern village of Hroza that killed 51.

One of the missiles landed in the street, leaving a crater, and the other hit a three-story building, setting it ablaze, according to Syniehubov.
Debris and rubble littered the street. Surrounding buildings were blackened by the blast, which blew out windows and damaged parked cars.
Yevhen Shevchenko, a resident of a nearby nine-story building, said he was in bed when the attack occurred. "There was a blast wave, a powerful explosion.
It blew out the windows and doors in the apartment," he said.
A day earlier, a Russian Iskander ballistic missile turned a village cafe and store to rubble in Hroza, a village in eastern Ukraine, killing at least 51 civilians, according to Ukrainian officials.
Around 60 people, including children, were attending a wake at the cafe when the missile hit, the officials said.
Kremlin spokesman Dmitry Peskov denied Friday that Russia was responsible for the Hroza attack. He insisted, as Moscow has in the past, that the Russian military doesn't target civilian facilities.
The Hroza victims made up most of the 54 civilians killed in the country over the previous 24 hours, Ukraine's presidential office said Friday.
The office of the U.N. human rights chief, Volker Türk, said he was "shocked and saddened" by the Hroza attack.
It said on X, formerly Twitter, that its human rights monitors intended to visit the site and collect information. "Accountability is key," it said.
Ukraine President Volodymyr Zelenskyy, attending a summit of about 50 European leaders in Spain to rally support from Ukraine's allies, called the strike a "demonstrably brutal Russian crime" and "a completely deliberate act of terrorism."
His visit to the summit aimed to secure more military aid, among other goals, and Zelenskyy said late Thursday that his efforts had produced results.
"We will have more air defense systems," he wrote on his Telegram channel. "There will be more long-range weapons."
The air defense systems are crucial as Ukrainian officials try to prevent attacks like the ones in Kharkiv and amid fears Moscow will resume concerted attacks on power facilities during the winter, in a repeat of its tactics last year when it tried to break Ukrainians' spirit by denying them electricity.
Zelenskyy is also fighting against signs that Western support for his country's war effort could be fraying.
Concerns over the resupply of Ukraine's armed forces have deepened amid political turmoil in the United States and warnings that Europe's ammunition and military hardware stocks are running low.
The Swedish government said Friday it plans to send to Ukraine a military aid package worth 2.2 billion kronor ($199 million), mainly consisting of 155-millimeter artillery ammunition.
"We are preparing for it to be a long war, therefore we need to design our support long-term and sustainably," Defense Minister Pål Jonson told a press conference. "It is now important that more countries step up to support Ukraine."
