MOSUL, Iraq, Iraqi security forces recaptured new areas from the Daesh militants in Mosul, as the troops reached the eastern bank of the Tigris River for the first time, the Iraqi military said.

In the eastern front, the elite forces of Iraq's Counter-Terrorism Service (CTS), continued their progress in two routes; the first one was advancing to the fourth bridge on the Tigris River, which bisects the city, and capturing the eastern bank, for the first time, in the battles of Mosul, a statement by the Iraqi Joint Operations Command said.

The battles left some 40 militants killed and two car bombs destroyed, as well as, destroying a vehicle carrying heavy machine gun, the statement said.

The second CTS route within the eastern front was advancing towards Baladiyah and Succar neighbourhoods, amid heavy clashes that resulted in seizing the southern parts of the two neighbourhoods, killing 43 extremist militants and destroying a vehicle carrying heavy machine gun, the source said.

In the south-eastern front, the Iraqi federal police and army soldiers continued their heavy street-to-street fighting against the militants in the neighbourhoods of al-Salam, Palestine, Domiez and Sumer, recapturing several buildings and killing some 25 militants, according to the statement.

In the northern front, the army, backed by international aircraft, fought sporadic clashes during clearing operation to many of the 168-building residential compound of Hadbaa, which were freed in the advance, which occurred on Friday, in the northern edges of the eastern side of Mosul, the statement said, adding that, the clashes left some 10 militants killed and three booby-trapped vehicles destroyed.

In south-west Mosul, the federal police forces repelled an attack by dozens of militants on the troops' positions at the village of al-Adhbah, killing 12 militants and destroying two vehicles carrying heavy machine gun, it said.

The troops made their new push into several neighbourhoods in the eastern side of Mosul, locally known as the left bank of the Tigris River.

The UN High Commissioner for Refugees (UNHCR), said in a recent report that, the military operations in Mosul, have pushed about 136,000 civilians to flee their homes in the city and its adjacent districts, since the beginning of military offensive in Oct, to reclaim the Daesh's largest stronghold in Iraq.

More than 1.5 million people were trapped in the city of roughly two million population previously. Cold winter worsened the conditions for the displaced people, who suffered severe shortages of food and water, while camps and other emergency shelters reached maximum capacity.
