Iraq crisis: Militants push towards Baghdad

13 June 2014 Last updated at 14:49 BST

The advance through Iraq of the Islamist militant group ISIS continues to cause alarm in Baghdad and beyond.

The Iraqi government insists it has a plan to defend the city, and the country's most senior Shia cleric has urged people to take up arms against the insurgents.

The UN says hundreds have been killed - with militants carrying out summary executions of civilians in Mosul.

Nick Childs reports.
