Hillary Clinton urges caution for US in Iraq

Former US Secretary of State Hillary Clinton says the US should withhold military support for Iraq until certain preconditions are met.

In an interview with BBC Newsnight, she said Prime Minister Nouri al-Maliki first had to show he was "inclusive".

Her comments came after President Barack Obama said the US was looking at "all options" in Iraq.

The Iraqi cities of Mosul and Tikrit have fallen to Sunni Islamist insurgents during a lightning advance.
