Islamist insurgents in Iraq have seized the city of Tikrit, their second major gain after capturing Mosul on Tuesday, security officials say.
Tikrit, the hometown of former leader Saddam Hussein, lies just 150km (95 miles) north of the capital Baghdad.
Iraqi PM Nouri Maliki has vowed to fight back against the jihadists and punish those in the security forces who have deserted.
The insurgents are from the Islamic State of Iraq and the Levant (ISIS).
ISIS, which is also known as ISIL, is an offshoot of al-Qaeda.
It controls considerable territory in eastern Syria and western and central Iraq, in a campaign to set up a Sunni militant enclave straddling the border.
