Baha Khatari, 20, was a member of the Abu Ali Mustapha Brigades, the military wing of the Popular Front for the Liberation of Palestine (PFLP).
The Israeli army confirmed the clash to AFP.
Khatari's death brought to 5,563 the number of people killed, most of them Palestinians, since the start of the intifada or Palestinian uprising in September 2000, according to an AFP count.
