Mohammed Abu Khedair , a Palestinian teenager who was abducted and killed in Jerusalem this week , died from being burned alive and hit on the head with a blunt object , according to Palestinian General Prosecutor Mohammed al-Auwewy , citing a medical autopsy . Al-Auwewy said the autopsy discovered traces of smoke inside the lungs of the 16-year-old , indicating that it was inhaled while the fire was burning . Mark Regev , spokesman for Israeli Prime Minister Benjamin Netanyahu , said his country is aggressively investigating the killing . `` We 'll get to the bottom of it and catch those responsible , '' he told CNN on Saturday . Relatives accuse Israeli forces of beating visiting U.S. teen . The teenager 's death sparked widespread outrage among Palestinians , many of whom believe he was killed in retaliation for the abduction and killing of three Israeli teens . Israeli authorities are investigating who killed Khedair and why , said Netanyahu . After the Palestinian teen 's funeral on Friday , more than 60 people were injured in clashes with Israeli security forces in parts of Jerusalem , according to the Palestinian Medical Relief Society , a group that said it was involved in evacuating injured Palestinians . It said the injuries mostly involved rubber bullets fired at the upper body and chest . Israeli police said 13 of their officers were slightly injured in clashes in the Jerusalem neighborhood of Shuafat , where Palestinian protesters were throwing rocks at police , who responded by firing rubber bullets and tear gas . Clashes erupt after Palestinian teenager 's funeral in Jerusalem . Meanwhile , a 15-year-old cousin of Khedair is at the center of a new controversy that 's become an international incident . Tariq Khdeir , 15 , a high school sophomore in Tampa , was visiting his Palestinian relatives in Jerusalem when he was attacked and detained , relatives told CNN . The family claims that Khdeir is seen in separate videos being held down and pummeled by men in the uniform of Israeli security forces . Israel 's Justice Ministry is investigating an incident that U.S. State Department spokeswoman Jen Psaki called `` troubling . '' Rockets from Gaza get Israeli response . Khedair 's death has raised the ire of many Palestinians in Jerusalem . But that city is hardly the only place in the region that 's fraught with tension . Gaza and Israeli communities within rocket 's reach have seen plenty of intermittent violence in recent weeks . This comes after Israeli authorities blamed Hamas -- the Islamist militant group that controls Gaza -- for the kidnapping and killing of the three Israel teens whose bodies were found earlier this week . Hamas has praised the kidnappings of the Israelis but denied that it was responsible for what happened . It also warned if Netanyahu `` brings a war on Gaza , the gates of hell will open to him . '' While it could still ratchet up significantly , the dangerous back-and-forth between the two sides continued this weekend . That includes more Israeli warplanes striking targets in Gaza , as well as more rockets being fired across the border into Israel early Sunday morning . Israel Defense Forces said in a press release that `` following constant rocket fire at ( southern ) Israeli communities , '' its aircraft targeted 10 `` terror sites '' in central and southern Gaza . The targets included `` concealed rocket launchers and a weapon manufacturing facility , '' the military said . And on Saturday , Israeli military aircraft targeted a militant in southern Gaza who earlier in the day fired rockets at the town of Ofakim in southern Israel , IDF said in a statement . Initial indications suggest that three rockets were intercepted above the area of Ashkelon , the military said . At least 14 rockets have been fired at Israel since midnight Saturday with one being intercepted by Israel 's Iron Dome above Be'er Sheva , according to IDF . Twelve rockets landed in Israeli territory and another fell in Palestinian territory . Opinion : Slain teens call for justice , not escalation . Netanyahu says of slain teens : 'May God avenge their blood '
