Assault on Tikrit?

Just days after announcing, and then scrapping a plan for an assault on Mosul to eject IS forces, news now comes that a substantial Iraqi force is assaulting Tikrit.

From the BBC:

Iraq has launched a military operation to recapture Saddam Hussein’s hometown of Tikrit from Islamic State (IS), Iraqi TV says.

Local media reported that forces were attacking the city, backed by airstrikes from Iraqi fighter jets.

Tikrit lies 150km (95 miles) north of the capital Baghdad and was seized by IS militants in June 2014.
