Russia launched a record 90 Shahed-type drones over Ukraine during the early hours of the new year, the Ukrainian air force said Monday, while Russia also reported Ukrainian attacks.

A 15-year-old boy was killed and seven people wounded after falling debris from one of downed drones hit a residential building in the city of Odesa, the head of the region’s military administration, Oleh Kiper, said. Debris also sparked a number of small fires, including at the city’s port.

In the western city of Lviv, Russian attacks severely damaged a museum dedicated to Roman Shukhevych, a controversial Ukrainian nationalist and military commander who fought for Ukrainian independence during World War II. University buildings in the town of Dubliany were also damaged, although no casualties were reported.

Meanwhile, four people were killed and 13 more wounded following Ukrainian shelling on Russian-occupied areas of Donetsk, according to the area’s Russian-installed leader, Denis Pushilin. Russian state media reported that a journalist was among the victims, but provided no further details.

One person was also killed and another wounded in shelling on the Russian border town of Shebekino, regional governor Vyacheslav Gladkov said.

The aerial strikes follow a series of heavy aerial bombardments that began on Friday, when Russia unleashed an 18-hour attack that one air force official described as the biggest aerial barrage of the war.

Shelling in the center of the Russian border city of Belgorod Saturday killed 21 people, including three children, local officials reported.

A further 110 people were wounded in the strike, said regional governor Vyacheslav Gladkov, making it one of the deadliest attacks on Russian soil since the start of Moscow’s invasion of Ukraine 22 months ag
