Coalition forces have captured nearly half of the terror capital in Iraq after six weeks of furious fighting.
The Iraqi military said ISIS’ “spirit is broken” – with supply lines cut and few fighters remaining.
But the troops now face jihadist snipers, suicide bombers and car bombs when moving from district-to-district in a bid to rid the city of the extremist group for good.
The masked elite Iraqi troop known as the Golden Division are the only brigades to have entered Mosul from the east.
Other forces have surrounded ISIS – but progress has been slowed over concern of civilian casualties.
Special forces commander Major General Abdul Ghani al-Asadi said: “The force left in front of us is small, unable to stop our advance.
“Their spirit is broken.
“We have killed more than 992 fighters on our front – plus more wounded.
“Their supplies and communications to the outside world are cut.
“They stage fewer suicide bombings.”
More than one million people are thought to be still in the battered city – and the Iraqi government has warned them to take cover during the final assault.
Defeating ISIS in Mosul – the death cult’s largest city and its last bastion in Iraq – is vital to destroying the so-called “caliphate”.
The group’s demonic leader, Abu Bakr al-Baghdadi, declared his new Islamic empire from the pulpit of Mosul”s Grand Mosque in July 2014.
