(IsraelNN.com) The IAF hit a house in the Sheikh Radwan neighborhood of Gaza City on Thursday evening. The strike targeted senior Hamas terrorist Nabil Abu el-Amrin.

Powerful secondary blasts were seen from the air after Amrin's house was hit, confirming IDF intelligence according to which the building was used to store large quantities of explosives and ammunition. It was not immediately clear if Amrin was killed in the strike.

On Thursday afternoon the IAF hit and killed Nizar Rayyan, making him the most senior Hamas terrorist to be killed by Israel in several years. Several others were killed in the blast as well.

Paramedics believe the dead are members of Rayyan's family who were not evacuated from the building despite receiving warnings from the IDF. Nine of the deceased have been identified as two of his four wives and seven of their children.

Gaza Residents Flee Inwards
Hundreds of Gaza residents have fled from neighborhoods bordering the western Negev, according to Ynet. Residents are fleeing inward from the el-Nada neighborhood near the Erez crossing and from villages at the northern edge of Gaza.

Residents are fleeing due to reports of a planned Israeli incursion. Israeli troops have gathered at the outskirts of Gaza, but so far have not entered the area.

Hamas issued threats on Thursday to Israeli soldiers, and said the group had trained thousands of women and girls to act as suicide bombers and kill any IDF soldiers who entered Gaza.

Rockets Continue, No Injuries
Gaza terrorists continued to launch rockets at Israel on Thursday evening, targeting the Eshkol and Sha'ar HaNegev regions with three attacks. The rockets hit open areas and did not cause injury.

Terrorists have fired more than 50 rockets since Thursday morning. One hit an eight-story building in Ashdod, causing heavy damage and sending several residents into shock. Eight others hit the city of Be'er Sheva, which was hit for the first time on Tuesday night. No injuries were reported in Thursday's attacks, but more than 50 people were treated for shock.
