The Palestinian health ministry said in a statement that Khalil Yahya Anis, 20, was "killed by live occupation (Israeli) bullets in the head in Nablus".
An official at Nablus' Al Najah hospital told AFP that two others were injured in the overnight clashes that erupted when Israeli forces entered the city to demolish the home of an alleged attacker.
An AFP journalist saw a group of young men surveying the damage to the apartment after dawn on Thursday. Twisted metal and piles of rubble littered the floor, and a gaping hole was left in a wall.
A local Palestinian security official, who did not want to be named, confirmed that Anis was a fighter, though he did not say with which group he was affiliated.
Witnesses told AFP that the army had demolished the flat of Osama Taweel, a prominent member of the Lions' Den militant group.
Israel regularly carries out demolitions of Palestinian homes in the occupied West Bank, and the new far-right government has made settlement building one of its top priorities.
Since the start of the year, at least 159 Palestinians, 21 Israelis, a Ukrainian and an Italian have been killed in violence linked to the Israeli-Palestinian conflict, according to an AFP tally compiled from official sources.
The figures include combatants as well as civilians and, on the Israeli side, three members of the Arab minority.
Israel has occupied the West Bank since 1967.
