The Palestinian was heading from the West Bank sector of Jenin to Israel when he was spotted at a checkpoint, police said, adding that border guards opened fire and killed him before he could attack them.
It was the latest shooting of a suspected Palestinian attacker since the start of unrest in early October that has triggered fears of a third Palestinian intifada, or uprising, against Israel.
Nine Israelis, 66 Palestinians and an Arab Israeli have been killed since the violence erupted, while dozens have been wounded.
On Friday the Israeli army returned the body of Kemil and those of six other Palestinians killed by Israeli troops or police to their families in what appeared to be an effort to ease tensions.
The funerals of the other six were due to take place later on Saturday.
