The Islamic State group put up fierce resistance to defend the city it seized more than two years ago and also claimed responsibility for deadly suicide attacks further south.
The elite Counter-Terrorism Service has been spearheading the attack on the eastern front of the three-week-old offensive on Mosul, Iraq’s largest military operation in years.
“Our forces are continuing to clear neighbourhoods including Al-Samah, Karkukli, Al-Malayeen and Shaqaq al-Khadra,” CTS Staff Lieutenant General Abdelghani al-Assadi told AFP.

The jihadists have given up some of its bastions in Iraq and Syria with barely a fight in recent months but its men began the defence of their last Iraqi hub with anger.
“Resistance is very heavy and they have suffered major losses,” Assadi said of IS.
Soldiers from the army’s 9th armoured division also battled jihadists in the southeastern neighbourhood of Intisar, an AFP correspondent reported, as forces attempted to increase their footprint in eastern Mosul.
They first entered the streets of Mosul on Friday and were met with what one officer described as stiffer than expected resistance from IS jihadists.
The assault allowed some civilians to flee the city, most of whose million-plus residents remained trapped inside, sheltering both from their jihadist rulers and incoming fire from government forces and US-led coalition aircraft.
Some of the first civilians to manage to escape the city proper arrived at a camp near Khazir in Kurdish-controlled territory on Saturday.
Abu Sara dodged gunfire, bombs, mortar rounds and coalition strikes to flee his neighbourhood of Al-Samah, such was his desperation to leave what many civilians who escaped IS rule describe as an open-air prison.
“We walked several miles, taking with us only the clothes we were wearing and white flags we waved the entire way,” said the 34-year-old, wearing a brown fake leather jacket.

While the corridors called for by aid groups to allow the safe passage of civilians have yet to materialise, arrivals in the displacement camps dotting the area have increased markedly.
The government said it had taken in 9,000 displaced people in the past two days.
The International Organization for Migration said a total of about 34,000 people had been displaced since the start of rhe offensive on October 17.
Relief organisations were fighting the clock to build up their shelter capacity ahead of the feared mass exodus from Mosul.
Despite IS leader Abu Bakr al-Baghdadi giving his fighters a pep talk on Thursday, urging them not to retreat from Mosul in a rare audio message, the outcome of the battle was in little doubt.
The jihadists, with an estimated 3,000 to 5,000 fighters in Mosul, could hold out for weeks and inflict heavy casualties on government forces but they are outnumbered about 10 to one.
The group’s ability to hit back with ground offensives elsewhere appears to be gone and IS has responded with a string of diversionary attacks, including spectacular operations in Kirkuk and Rutba.
On Sunday, it claimed responsibility for three suicide attacks in Tikrit and Samarra, the two main cities in Salaheddin province north of Baghdad.
Iraqi officials spoke of only two bombers, one who detonated an explosives-rigged vehicle at the southern entrance to Tikrit, and another who blew up an ambulance in Samarra.
Jassem al-Jbara, the head of Salaheddin province’s security committee, said that the Tikrit attack killed 12 people and wounded 20, while six died and 12 more were injured in Samarra.
IS identified two of the bombers as “Al-Moslawi” — a nom de guerre that would indicate they were from Mosul, though it could be a propaganda attempt to link militants from other areas with the ongoing battle for Iraq’s second city.
Prime Minister Haider al-Abadi, who has visited the Mosul front lines several times since the offensive started, has vowed to rid the country of IS by the end of the year.
Retaking Mosul could effectively end the IS group’s days as a land-holding force in Iraq and deal a death blow to the “caliphate” Baghdadi proclaimed in the city in June 2014.
