Iraqi forces have repelled counter-attacks by so-called Islamic State (IS) as they push the group into a corner of Mosul's Old City, as stated by BBC.
IS deployed suicide bombers in different parts of the northern city but the affected areas were brought under control, Iraqi officials say.
The Iraqi offensive to remove IS from the city is in its final phase.
The military has announced it has captured al-Faruq district on the north-western side of the Old City.
Iraqi TV said the national flag had been raised in the district, which is opposite the al-Nuri mosque and famed crooked minaret destroyed by IS.
The operation to retake Mosul, seized by IS in 2014, began last October.
The government announced the liberation of the eastern half in January 2017, but the west of the city, with its narrow streets, has proved more difficult.
Nevertheless, IS is now confined to 2.5 sq km (a square mile) of territory.
