Three Palestinians and one Israeli have been killed after a series of attacks in the West Bank, the latest incidents in a nearly two-month wave of violence.
Reports say no Israelis were seriously wounded in the first two attacks, but a young woman who was stabbed in the third attack has died from her wounds, a hospital official said.
In the first attack, a Palestinian woman who tried to stab an Israeli was run over by a Jewish settler and then shot dead by soldiers.
The Israeli military said in a statement that the attack occurred at a junction south of Nablus, adding that "forces and a bystander responded to the immediate threat, shooting the attacker".
Palestinian security officials confirmed she had died of her wounds. The attack occurred in an area known to Israelis as Samaria Junction and to Palestinians as Hawwara Junction.
Later, a Palestinian man was shot dead after attempting to drive into civilians with a taxi before charging at them with a knife.
"A Palestinian man at Kfar Adumim junction in a Palestinian taxi tried to run over civilians," a statement said.
"When he failed, he exited the car with a knife and attempted to stab. The terrorist was shot by a civilian and died of his wounds."
The third attack took place near the Gush Etzion block of settlements.
Israeli media reports said the female victim of the attack was 20 years old. She sustained injuries to her head and chest and later died in hospital.
Her 34-year-old Palestinian attacker was shot dead by security forces.
The attacks were the latest in the wave of violence since 1 October that has left 88 dead on the Palestinian side, including one Arab Israeli, as well as 16 Israelis, an American and an Eritrean.
Many of the Palestinians killed have been alleged attackers.
On Saturday night police arrested a Palestinian who allegedly stabbed four Israelis in southern city Kiryat Gat.
