Attack on Gaza City

On the morning of January 11, the IDF started the third stage of the operation with an attack on the suburbs of Gaza City. Israeli forces pushed into the south of the city and reached a key junction to its north. During their advance Hamas and Islamic Jihad ambushed Israeli troops at several locations and heavy fighting ensued. Additionally, the IAF reported that Hamas operatives had tried to shoot down an IAF fixed wing aircraft with anti-aircraft missiles for the first time since operations in Gaza began. Heavy machine gun fire against helicopters had also been unsuccessful.

On January 12, the IDF reported that it started deploying reserve forces in Gaza.

On January 13, Israeli tanks continued their advance toward the headquarters of Hamas' preventative security building from the al-Karramah neighborhood in the northwest and the Tel al-Hawa neighborhood in the northeast. Before dawn, during the night, troops advanced 300 yards into Tel al-Hawa, a neighborhood which has several high-rise buildings. As troops entered the narrow streets heavy street fighting with militants ensued leaving 3 Israeli soldiers wounded and 30 Hamas militants dead or wounded, according to the IDF. By morning IDF soldiers were still advancing slowly towards the city center and several buildings were in flames in Tel al-Hawa, where most of the fighting took place.

On January 15, Israeli artillery started a bombardment of the city while fighting was still going on in the streets. Three high-rise buildings were shelled. The Israeli military reported to have killed dozens of militants, since breaching the city limits four days earlier, while they suffered 20-25 soldiers wounded. Among buildings shelled were the al-Quds hospital, Gaza's second-largest, in the Tal El Hawa district; the Al-Shuruq Tower's 13th floor, housing journalists: and the headquarters of the United Nations Relief and Works Agency (UNRWA). Because of this, the United Nations stopped humanitarian aid in and outside the Gaza Strip.
