KYIV, Ukraine >> Russian forces launched a missile attack on the Kyiv area for the first time in weeks Thursday and pounded the northern Chernihiv region as well in what Ukraine said was revenge for standing up to the Kremlin.

Ukrainian officials, meanwhile, announced a counteroffensive to take back the occupied Kherson region in the country’s south, territory seized by Russian President Vladimir Putin’s forces early in the war.

Russia attacked the Kyiv region with six missiles launched from the Black Sea, hitting a military unit in the village of Liutizh on the outskirts of the capital, according to Oleksii Hromov, a senior official with Ukraine’s General Staff.

He said that the attack ruined one building and damaged two others, and that Ukrainian forces shot down one of the missiles in the town of Bucha.

Fifteen people were wounded in the Russian strikes, five of them civilians, Kyiv regional Gov. Oleksiy Kuleba said.

Kuleba linked the assaults to the Day of Statehood, a commemoration that President Volodymyr Zelenskyy instituted last year and Ukraine marked for the time Thursday.

“Russia, with the help of missiles, is mounting revenge for the widespread popular resistance, which the Ukrainians were able to organize precisely because of their statehood,” Kuleba told Ukrainian television. “Ukraine has already broken Russia’s plans and will continue to defend itself.”

Chernihiv regional Gov. Vyacheslav Chaus reported that the Russians also fired missiles from the territory of Belarus at the village of Honcharivska.

Russian troops withdrew from the Kyiv and Chernihiv regions months ago after failing to capture either.

Elsewhere around the country, five people were killed and 25 wounded in a Russian rocket attack on the city of Kropvynytskyi.
