KYIV, Ukraine >> A Ukrainian attack Friday on a town in Russia’s Kursk border region using U.S.-supplied missiles killed six people, including a child, a senior local official said. The attack came hours after Ukrainian authorities said a Russian ballistic missile strike on Kyiv killed at least one person and wounded 13.

Moscow claimed the Kyiv strike was in response to a Ukrainian strike on Russian soil using American-made weapons earlier this week.

Ten other people in the Kursk town of Rylsk, including a 13-year-old, were hospitalized after Friday’s strike with HIMARS missiles, Kursk acting Gov. Alexander Khinshtein said. He provided no further details.

Russia is trying to push back a Ukrainian incursion into Kursk that was launched in early August, but Ukraine’s troops are dug in.

The truck-mounted HIMARS launchers fire GPS-guided missiles capable of hitting targets up to 50 miles away. The mobile launchers are hard for the enemy to spot and can quickly change position after firing to escape airstrikes.

President Joe Biden last month authorized Ukraine to use U.S.-supplied missiles to strike deeper inside Russia, easing limitations on the longer range weapons. The move was a response to Russia deploying thousands of North Korean troops to reinforce its war effort, officials said.

Shortly before sunrise Friday, at least three loud blasts were heard in Kyiv. Ukraine’s air force said it intercepted five Iskander short-range ballistic missiles fired at the city. The attack knocked out heating to 630 residential buildings, 16 medical facilities and 30 schools and kindergartens, the city administration said. Falling missile debris caused damage and sparked fires in three districts.
