Nine people were killed in Russian attacks on Ukraine, including a major airstrike on Kyiv that authorities described as the most severe in two weeks. The assault left four dead and 23 injured in the capital, where a fire broke out at the Pechersk Lavra monastery, a historic and spiritual landmark recognized by UNESCO. The head of Kyiv’s military administration, Timur Takachenko, said the monastery suffered serious damage.

The Pechersk Lavra, founded in 1051, is one of Ukraine’s most significant religious and cultural sites. Residents of the monastery took shelter underground as the fire spread. The attack marked the most intense Russian strike on Ukraine since early June.

In a separate incident, five people were killed and at least five others injured in another Russian attack on Kharkiv, Ukraine’s second-largest city, according to reports citing Reuters.
