A Palestinian man stabbed and seriously wounded an Israeli in the southern West Bank before being shot dead, the army said on Monday.
"The assailant stabbed the Israeli in the neck, wounding him severely. The attacker was shot on site, resulting in his death," a statement from the military read.
A military spokeswoman later clarified to AFP that the assailant was killed by soldiers.
Emergency medical services spokesman Magen David Adom said they had evacuated a 19-year-old Israeli with a stab wound in his neck to Shaare Zedek hospital in Jerusalem, which said he was in a "serious and unstable condition."
Palestinians named the dead attacker as Raed Jarradat, in his 20s, from the village Sair, north of Hebron and close to the Beit Einun junction where the attack took place.

On Sunday, a man from Sair was wounded by gunfire shortly after an Israeli was stoned and stabbed nearby. The Israeli, who was moderately wounded in the attack, had managed to fire his pistol at his assailant.
Also on Sunday, a 17-year-old Palestinian girl was shot dead while allegedly trying to knife Israeli border police in Hebron, the flashpoint West Bank city where many of the incidents in nearly a month of Palestinian attacks have taken place.
Clashes between Palestinians and Israeli forces erupted at Jerusalem's Al-Aqsa mosque compound in September as Muslims protested an increase in Jewish visitors during their religious holidays.
According to the status quo in place since Israel seized the complex from Jordan in the 1967 war, Jews may visit the site but are forbidden from praying at what they call the Temple Mount.
Clashes at Al-Aqsa spiralled into a wave of attacks against Israelis, leaving eight dead since the beginning of October. One Israeli Jew and one Eritrean have also been killed after being mistaken for attackers.
Monday's attack takes the number of Palestinians killed in attempted attacks and clashes to 54.
An Israeli Arab attacker has also been killed.
