Iraqi forces and mainly Shi'ite militia battling to wrest full control of the city of Tikrit from Islamic State militants paused their offensive for a second day on Saturday as they awaited reinforcements.
A source in the local military command centre told Reuters military commanders had "reached a decision to halt the operation until a suitable, carefully set plan is in place" to break into central Tikrit.
The source, speaking by phone from near Tikrit, said the Iraqi forces and Iranian-backed Shi'ite militias known as Hashid Shaabi (Popular Mobilisation) were waiting for reinforcements from "well-trained forces". He did not give a timeline for the arrival of the reinforcements.
"We do not need a large number, just one or two thousand. We need professional personnel and soldiers," he said, explaining they were needed to engage in street-by-street battles with Islamic State fighters who have booby trapped many buildings in the city and laid improvised explosive devices and roadside bombs.
