The assault is aimed at sealing the siege of the Old City, where die-hard jihadists are preparing for a bloody last stand.
Iraqi forces thrust into west Mosul from the north on Thursday, opening a new front in the more than six-month-old offensive to dislodge the Islamic State group from the country's second city.
The assault is aimed at sealing the siege of the Old City, where die-hard jihadists holding huge numbers of civilians hostage are preparing for a bloody last stand.
Forces from the army, the interior ministry and the police
"began breaching the western side from the north," the Joint Operations
Command (JOC) coordinating the war against IS said in a statement.
"Now
your sons are fighting and striking the enemy's defences... They
rejoice in victory or martyrdom for the sake of liberating the rest of
the city of Mosul from Daesh (IS) terrorists," it said.
The JOC said the targets of the latest push were northwestern neighbourhoods on the edges of Mosul called Musharifah, Kanisah and Al-Haramat.
The
federal police issued a statement confirming the new operation, which
comes after a relative lull in fighting around the Old City where most
remaining jihadists are believed to be holed up.
It said Iraqi forces had already captured a small outlying village called Hsunah and a nearby gas factory.

Thursday's
operation opens a new front in the effort to wrest back west Mosul from
IS which started in mid-February and saw thousands of Iraqi forces
retake most southern and western neighbourhoods.
An
advance from the north will eventually leave the jihadists completely
trapped in the narrow streets of the Old City, albeit with a large
civilian population they have been using as human shields.
Civilian displacement
The United Nations said up to 400,000 people might be trapped in the densely populated Old City, which lies just west of the Tigris River that divides Mosul.
The
Iraqi immigration ministry said this week that the number of people who
were displaced since the start of the offensive on Mosul on October 17
had topped 600,000.
The vast majority of
them fled homes on the west side of the Tigris, where the fighting has
been more intense than in east Mosul, which was declared retaken by the
government in January.
Of the more than 120,000 people displaced from east Mosul, the ministry said only 42,000 were still in camps.
The recapture of Mosul by the Iraqi security forces would deal a death blow to the "caliphate" IS proclaimed over large parts of Syria and Iraq nearly three years ago.

It
would represent a major symbolic setback for the group whose
unprecedented experiment in jihadist statehood was heralded by the
conquest of Mosul in June 2014.
The northern city is where Iraq-born IS supremo Abu Bakr al-Baghdadi -- who has urged his men to defend Mosul to the death -- made his only public appearance in July that year.
According
to the authorities, IS now controls less than seven percent of Iraq,
down from more than a third of the national territory in 2014.
The
jihadists have in recent days carried out diversionary attacks against
security forces from their desert hideouts in the western province of Anbar.
At least 26 members of the army, police, tribal forces and border guard died in the attacks but the jihadists' "state" has looked doomed for months.
Observers have warned that, with other anti-IS forces also pressing a major offensive on their last major Syrian bastion of Raqa, the jihadists could increasingly revert to guerrilla tactics and bombings of civilian targets
