 Russia said on July 17 that it had launched an investigation over an apparent attack on the Crimean Bridge, a key artery for Russian troops fighting in Ukraine. Video released by Russia's investigative committee on Monday showed its investigators collecting debris on the damaged section of the bridge. Russia said two people had been killed and one person wounded in the attack, which had blamed on Ukrainian special services. Three Ukrainian media outlets quoted unnamed sources as saying Ukraine's domestic security agency and Navy were behind Monday's incident on the Crimean Bridge and that they had used seaborne drones to attack it.
