ITV News' Middle East Correspondent Geraint Vincent reports:
Israeli police said a woman in her mid-20s was killed while two other people were wounded during a stabbing attack in the West Bank.
The woman was killed when a man stepped out of a car at a bus stop in front of the Alon Shvut settlement, then stabbed three people before he was shot by a security guard. The attacker is in a serious condition.
A teenage girl has been killed in a stabbing attack in the West Bank in which the suspected Palestinian attacker was shot, according to Israel's national rescue service.
The girl was stabbed along with two other Israelis at a bus stop outside the West Bank settlement of Alon Shvut. The attacker was shot and wounded by a security guard at the scene.
Israel Defense Forces Spokesman Peter Lerner said on Twitter it was a "sad day".
Three Israelis have reportedly been stabbed during an attack at the Alon Shvut junction in the Gush Etzion area of the West Bank, just hours after a soldier was left in a "grave condition" when he was also stabbed in a Tel Aviv train station.
The suspected terrorist who carried out the stabbing in the West Bank settlement was shot by a security guard at the scene.
An Israeli soldier who was stabbed by a Palestinian in a Tel Aviv train station is in a "grave condition", a hospital spokesman said.
The suspect was arrested at the scene and is currently under police interrogation.
The attack comes after the fatal shooting of an Israeli Arab by a policeman early on Saturday in the town of Kfar Kana, which gave new impetus to the ongoing tensions.
Arab citizens make up some 20% of Israel's population. They enjoy full citizenship but share the ethnicity and culture of the Palestinians in the occupied territories.
They have long complained of discrimination and often identify with Palestinian nationalism, rather than Israeli.
Dozens of Palestinian students attacked the car of a British diplomat with metal rods, as he arrived to give a speech at a West Bank university.
The consul general, Sir Vincent Fean, was due to speak at the Palestinian university of Birzeit but the event was cancelled due following the incident.
A representative for the British Consulate in Jerusalem confirmed the incident. They said: "The British Consul General, Sir Vincent Fean, visited Birzeit University today. His intention had been to engage in an open dialogue with the student community about the UK’s policies in the Middle East.
"Sir Vincent had hoped to underline Britain’s deep commitment to the creation of a Palestinian state, and the urgency of progress on the peace process in 2013."
"Sadly, such a dialogue was not possible on this occasion. Sir Vincent remains absolutely committed to building his relationship with the Palestinian student community, and hopes to have the opportunity to pursue this dialogue in future,” the British representative added.
