JERUSALEM, Israel - Ten days after being critically wounded by an anti-tank missile that hit his school bus, 16-year-old Daniel Viflic succumbed to his injuries on Sunday.

Moments before the missile hit, dozens of children had been dropped off. Only Daniel and the bus driver - who sustained shrapnel wounds to his leg - remained. Hamas claimed responsibility for the attack.

Paramedics resuscitated Daniel at the scene before he was air lifted to Soroka Medical Center Trauma Unit in Beersheva. Last week, doctors said his condition had deteriorated to "extremely critical." 

Following the attack, Palestinians fired 120 rockets, missiles, and mortar shells on southern Israel. The IDF responded by targeting the terror infrastructure, including arms smuggling tunnels, weapons warehouses, and launch sites.

Hamas and Israel agreed to a shaky ceasefire at the beginning of the week. On Saturday, Palestinians fired Grad missiles at Israel's coastal cities of Ashkelon and Ashdod. Israel responded by successfully targeting two terror sites in northern Gaza.

"The IDF will not allow the Israeli southern communities to continue living under constant threat and will continue to respond with determination to any attempt to use terror against the citizens of Israel. The IDF holds the Hamas terrorist organization solely responsible for any terrorist activity emanating from the Gaza Strip," the IDF Spokesperson's Office said.
