Hamas said that Mohammed al-Ar'ir, 19, was killed when a tank shell targeted him near Nahal Oz crossing point. In a message sent to journalists' mobiles, the armed wing of Hamas said the youth was on a "Jihad mission," but did not elaborate.
Medical sources said the youth was dead when taken to al-Shifa hospital in Gaza with shrapnel in most of his body at 7:45 a.m. (0545 GMT).
The death of al-Ar'ir brings the death toll to 15 militants killed since a new wave of violence hit the Hamas-controlled territory on Nov. 4. During this period, armed Palestinian groups resumed rocket attacks into Israeli border towns to retaliate a series of Israeli army operations.
The latest violence rocked the five-month-old Egyptian-brokered ceasefire.
Meanwhile, Israel kept the crossing points to Gaza Strip closed for the 16th successive day.
