(Reuters) - Ukraine's air defence systems shot down seven out of eight Russia-launched Shahed drones overnight, the country's air force said on Thursday.

       Drones were downed in three central and southern regions, the air force said on the Telegram messenger. It was not clear whether the drone that was not shot down reached its target.

       The Russian Defence Ministry also said it thwarted a Ukrainian drone attack over Moscow-occupied Crimea overnight.

       There was no immediate comment from Ukraine.
