Iraqi security officials say militants from the al-Qaeda-inspired group Islamic State of Iraq and the Levant (ISIS) have seized the northern city of Tikrit.

They captured Mosul yesterday, facing little resistance from Iraqi armed forces. Up to half a million people have fled their homes in Mosul.

ISIS are now heading south into Samarra, and are reported to be about 80 miles from Baghdad.
