Senior Ukrainian officials visited Washington on Tuesday seeking U.S. support against Russia, as Kyiv showed its ability to fight on by setting off an explosive device under a bridge that has become a symbol of the Kremlin's claims on Ukrainian territory.

Ukraine said on Tuesday that it had hit the bridge connecting Russia and the occupied Crimean Peninsula with explosives planted underwater, in its third attack on the vital supply line for Moscow’s forces since the full-scale war began in 2022.
