A Palestinian man was shot dead by Israeli forces after stabbing a border policeman in the northern West Bank on Saturday, the army and Palestinian medics said.
The military said that "an assailant stabbed a Border Police officer at the Beta Junction, south of Huwara", in the second stabbing attack of the day and the third in less than a week.
"Forces on scene responded immediately, shooting and wounding the attacker," it said in a statement.
Abdelhalim Jaafreh, head of the Red Crescent in Nablus, told AFP the suspected assailant died of his wounds.
"He was critically wounded by five bullets: we tried to save him but he died," he said.
Palestinian president Mahmud Abbas identified him as 21-year-old Rafiq Taj from Nablus, correcting earlier reports that he was a 16-year-old named Ahmad Taj, and condemned his "killing by the occupation forces".

Abbas noted the "dangerous escalation" in the form of "daily killing with no end," and in a statement called on the international community not to remain silent.
The border policeman, who had been on patrol with other officers when he was attacked from behind and stabbed in the back, was lightly wounded, police said.
Earlier on Saturday, a Palestinian was shot after stabbing an Israeli soldier near a checkpoint on highway 443 in the central West Bank, the army said.
Both the Palestinian and the soldier were lightly wounded in that attack, which took place at the "Bel" crossing not far from Ofer military prison.
And last Sunday Israeli troops shot dead a Palestinian who stabbed and lightly injured an Israeli civilian at a petrol station on highway 443.
