The streets of Gaza were filled with celebration upon the news that four young Israelis were killed and many more wounded in an Islamic terror attack.

Hamas  supporters rallied through the center of Jabalia in the Gaza Strip on Sunday in praise of Fadi al-Qanbar, who mowed down a group of officer cadets in Jerusalem earlier in the day, killing 4 and wounding 15.

The terrorist, 28, attacked a crowd of IDF soldiers in the eastern Jerusalem Armon Hanatziv neighborhood. The dead victims ranged in age from 20 to 22.

Israeli leaders confirmed that the terrorist was an Islamic State (ISIS) sympathizer, noting that the attack was similar to recent mass-casualty ISIS acts of terror in Europe.
