A four-year-old boy was killed and eight were wounded on Friday following a series of rocket and mortar shell barrages launched from Gaza. Some 100 rockets and mortar shells were fired at Israel over a 24-hour period.

Daniel Tragerman, the child killed Friday afternoon after a mortar shell hit a car in a kibbutz by the Gaza border, is the first Israeli child to be killed during this round of violence.

A military source initially said that the shell was fired from a school used by UNRWA to shelter Gaza refugees, but the Israel Defense Forces later retracted the report.

"After further review, the school the mortar was launched near from is not being used as a shelter by UNRWA but rather a shelter maintained by Hamas authorities in Gaza," IDF Spokesperson Peter Lerner tweeted.

Two separate rocket attacks in Ashdod wounded six people in total. One of the casualties is a 25-year-old man who is in serious condition, the others are all in light condition. One person was moderately wounded in an attack on Be'er Sheva, as well.

Prime Minister Benjamin Netanyahu expressed his condolences to the child's family, adding that the IDF and Shin Bet would intensify operations in Gaza.

"In this difficult moment, I wish to strengthen the people of Israel," Netanyahu said. "Hamas will pay a heavy price for this terrible terrorist attack. The IDF and the Shin Bet will intensify their operations against Hamas and the terrorist organizations in Gaza until the goals of Operation Protective Edge will be reached."
