Iraq's foreign minister warns of danger from Isis

Iraqi Foreign Minister Hoshyar Zebari has told the BBC's John Simpson that the ''fight'' in Iraq with militant groups has regional and global implications.

He also warned of a ''clear and present danger'' from militant groups such as the Sunni insurgent group, Isis.

US Secretary of State John Kerry has arrived in Iraq's capital, Baghdad, as Isis expands its control of towns across north-western Iraq.
