The sprawling offensive by militants in Iraq has now reached the country's largest oil refinery - but it's unclear who has control over the strategic target.
On Tuesday morning, the state-run Iraqiya news agency said Iraqi security forces still control the Baiji oil refinery.
The report also said Iraqi special forces have killed the militant leader who led the attacks against the refinery and goes by the name of " Abu Qutada."
But hours earlier, militant fighters believed to be from the Islamic State in Iraq and Syria (ISIS) seized the refinery, several Iraqi security sources told CNN.
CNN cannot independently confirm either claim.
The Baiji refinery, in the northern Salaheddin province, is a crucial resource because it refines much of the fuel needed for domestic consumption. Long lines have already formed at many gas stations across the country.
