MOSCOW (Reuters) -Nine people, including seven children, were killed on Tuesday and many more badly wounded after a lone teenage gunman opened fire in a school in the Russian city of Kazan, local authorities said, prompting a Kremlin call for tighter gun controls.
Two children could be seen leaping from the third floor of the four-storey School Number 175 to escape as gunshots rang out, in a video filmed by an onlooker that was circulated by Russia's RIA news agency.
