KIRKUK: Iraqi security forces advanced into militant-held Tikrit on Tuesday in an assault aimed at revitalising flagging efforts to retake the city, officials said.

Security forces began the attack in morning and have succeeded in retaking government facilities in the city's south.

“Iraqi forces began a military operation to liberate the city of Tikrit and our forces were able to control the southern part of the city,” Ahmed Abdullah Juburi, the governor of Salaheddin province of which Tikrit is the capital, said.

An army colonel said the police academy and a hospital had been retaken, and Juburi confirmed those facilities were in government hands, along with the governorate headquarters.

A major operation to retake Tikrit began more than two weeks ago, but it bogged down south of the city, which is the home town of executed Iraqi dictator Saddam Hussein.

Militants seized Tikrit on June 11 as part of a sweeping militant-led offensive that has overrun large areas of five provinces since it began last month.

Security forces folded under the weight of the initial onslaught, in some cases shedding uniforms and abandoning vehicles to flee.

They have since performed better, but have still struggled to regain ground from militants in offensive operations.
