Israeli troops have arrested a Palestinian youth with a knife who tried to stab a soldier at a checkpoint near Nablus in the northern West Bank.
The teenager was arrested at a checkpoint south-east of Nablus
Troops opened fire at the teenager but he did not appear to be wounded. Another Palestinian passer-by was hit by shrapnel, reports said.
It is the second such attack in two days in the Israeli-occupied West Bank.
On Tuesday, a woman was shot dead after she lunged at a woman soldier at another checkpoint outside Nablus.
Witnesses said 16-year-old Uday Mleitat ran towards a female soldier at the Beit Furik checkpoint on Wednesday shouting "God is greatest" but she was able to elude him.
"The soldier escaped the knife blow and the commander of the checkpoint opened fire towards the assailant," said an Israeli army spokeswoman.
Threat of attack
No group has claimed responsibility for the second attempted stabbing although the al-Aqsa Martyrs Brigades militant group claimed responsibility for the previous attack, attributed to Haifa Hindiya, 30, a mother of five.
"We will continue martyrdom operations throughout Palestine until the occupation leaves," the group said in a statement published on the internet.
The group said it was not committed to the truce agreed in February between the major Palestinian militant organisations and PA President Mahmoud Abbas.
The Israeli army said Hindiya was knocked to the ground after lunging at a woman soldier with her knife, and was shot dead when she tried to get up again and attack a second time.
The soldier received minor injuries during the attack.
Israel has occupied the West Bank, along with the Gaza Strip and East Jerusalem, since 1967.
Israeli human rights group B'Tselem says the army maintains 53 permanent military checkpoints in the West Bank.
About half of them prevent Palestinian traffic entering Israel and the rest control traffic between Palestinian towns, constituting "the most severe restriction on movement", the group says.
