A USA and an Iraqi government official say Prime Minister Haider al-Abadi is in talks with the Trump administration to keep American troops in Iraq after the fight against the Islamic State group in the country is concluded.
An Iraqi official told Stars and Stripes about five bases near Mosul and the Iraq-Syria border where it would make the most sense to station USA soldiers.
It said Iraqi forces had already captured a small outlying village called Hsunah and a nearby gas factory in the renewed push.
Some US forces are carrying out combat operations with Iraqi forces on and beyond front lines in the fight against IS. "I imagine we'll be in this fight for a while and we'll stand by each other". Mr. Trump and others have criticized the Obama administration for agreeing to what they say was a too-hasty US withdrawal from Iraq in 2011, with Islamic State eventually filling the security vacuum three years later.
The Pentagon has close to 7,000 United States troops in Iraq, many not publicly acknowledged because they are on temporary duty or under specific personnel rules.
Al-Baghdadi is believed to have fled the city, but Iraqi forces have only inched toward their goal of retaking the symbolic mosque and raising their country's flag since closing to within a few hundred yards of it in late March.
Separately, Captain Ali al-Bahadoli of Counter-Terrorism Service (CTS) said government forces had lobbed a barrage of missiles at an area west of Mosul, killing scores of Daesh militants.

The officer is on leave while police investigate, but the boy's family wants him fired and criminally charged, their lawyer said. Authorities say they were in an unmarked vehicle when two other vehicles pulled up alongside the officers and opened fire.
Meanwhile, the bulk of the Iraqi force, including the elite, USA -trained Counter-Terrorism Service and federal police units, advanced from the city's southern outskirts. The numbers were wound down eventually to 40,000 before the complete withdrawal in 2011.
"It is open to all worldwide expertise to meets the aspirations of Iraq to build military institutions and security apparatuses that enjoy full readiness to face any future security challenges, whether external or internal and in accordance with the requirements of Iraqi national sovereignty".
Observers warn that jihadists could increasingly resort to using guerrilla tactics and bomb civilian targets, as anti-IS forces are also pressing a major offensive on their last major bastion of the terrorist group in Syria, the city of Raqqa.
Jafar al-Husseini, a representative from the Kataib Hezbollah militia - who are closely linked to Iran - said the army and paramilitaries were strong enough to defend Iraq themselves.
Influential Shia cleric Muqtada al-Sadr has long criticised the presence of U.S. troops in Iraq, even going so far as to describe them as a potential "target" for his supporters.
Last October, the Iraqi army - backed by a US -led air coalition - began a wide-ranging operation to retake Mosul from ISIL, which the terrorist group overran in mid-2014.
