Battle for Sinjar: 'There are snipers. We need to be careful'

Kurdish forces have launched what they say is a major offensive to drive militants of so-called Islamic State out of the town of Sinjar, in the north-west of Iraq.
Sinjar was captured in August last year by the militants who attacked the mainly Yazidi population, killing many of the men and enslaving women and children.
