Hannah Bladon, 20, (pictured) was stabbed to death on a Jerusalem train

The British tourist who was killed during a knife attack in Israel on Good Friday has been named as Hannah Bladon.

The 20-year-old was stabbed multiple times in the abdomen with a kitchen knife on a tram close to the Old City, where thousands of Christians had gathered.

Police have arrested Jamil Tamimi, 57, a Palestinian man from East Jerusalem who was described as mentally unstable, after onlookers wrestled him to the ground.

Ms Bladon, who was a student at the University of Birmingham, travelled to Israel to study at the Hebrew University of Jerusalem.

Medics performed CPR on the young woman at the scene before she was taken to hospital in critical condition, where she later died.

In a Facebook post earlier this year she wrote she was 'OK' after a wave of terror attacks in the country.

She said: 'Thanks guys. I'm ok thanks! Security is really tight on campus so no worries at mo (sic)!

'Managed to see a lot of sites before starting my classes today so defo (sic) having a great time! Xx'.

Mark Regev, Israel's ambassador to the UK, said: 'My thoughts are with the family and friends of UK student Hannah Bladon, who was murdered in a senseless act of terror in Jerusalem today.'

During the shocking attack, an off-duty policeman pulled an emergency brake and tried to intervene.

He told the Israeli Police Spokesmanship: 'I was on the Jerusalem Light Rail with my family and during the journey I heard shouts of 'attack, attack'.

'I immediately pulled on the manual emergency break of the train, ran to the scene of the attack and charged at the attacker, neutralising him so that he cannot continue to harm innocent people.'

The Hebrew University of Jerusalem said: 'The Hebrew University and the Rothberg International School express our deep sorrow over the murder of a British student, Hannah Bladon, in today's attack.

'We extend our deepest condolences to her family and we share in their sorrow.

'The university condemns such acts of terror that harm innocent people, and especially a student who came to Jerusalem to study and widen her academic horizons.

'The university administration and staff will provide all necessary support to students, faculty members and their families in Israel and around the world.

'Hannah Bladon came to the Hebrew University as part of a student exchange from the University of Birmingham.

'Hannah began her studies here at the end of January 2017 and was supposed to continue her studies until the end of the current semester.'

Arye Jaffe, paramedic from United Hatzalah medical organisation, told Mail Online: 'There was a lot of blood. It was a big mess.

'There was a bunch of policemen already there and there were police medical and civilians treating her.

The British woman was taken to hospital in critical condition with multiple stab wounds to her abdomen, but later died from her injuries

'I tried to get near her head where it was possible to manage the other medics and to manage the victim's breathing.

'After stopping the blood I took steps to reduce the pressure on he chest and put a tube in to her to help her to breathe.

'I saw that the pulse had stopped and tried to stimulate her heart mechanically and then with medicine.

'She had extreme injuries in her upper abdomen and her extremities and as I was treating her, she lost her pulse.

'We tried CPR and when ambulance arrived to take her to the ICU I went with them, assisting them to the hospital, where doctors attempted open hear surgery to save her, but it was unsuccessful.'

The Foreign Office confirmed a Briton's death, saying it is supporting her family.

The University of Birmingham said it was 'deeply saddened' over Ms Bladon's death and said it would be supporting any students affected.

It was reported that Hannah took courses on Bible Studies, archaeology and religion at the university's Rothberg International School. She had been studying religion at the University of Birmingham since 2015.

Officers said the attacker got on the tram and rode one stop before launching his knife attack.

A police spokesman said the suspected attacker had tried to commit suicide earlier this year.

Miriam Levy, 32-year-old medic with Magen David Adom, added: 'There was a lot of blood everywhere and a young woman on the ground of the train.

'We tried CPR and evacuated her to the hospital as soon as possible.

The attack happened on a tram near the Old City, which was packed with thousands of Christians celebrating Good Friday

'There was a lot of noise when we got there, there was a lot people trying to treat her and help her. We had to ask the police to get all the people who couldn't help to move away.

'She was stabbed all over the upper part of her body -- chest, abdomen, limbs. it was a very serious stabbing.

'I've not seen this kind of severity apart from in hospitals -- it was my first time seeing it out in the field.

'I felt pity for this woman, she was so young, and on the other hand I needed to try to stay focused.

'It's so awful that a British woman came here to visit and this happened -- it makes me sad. Israel is more than this, but it's this kind of thing that leaves the hardest marks.'

A pregnant woman in her early 30s injured her stomach after the tram came to a sudden stop and a man in his early 50s hurt his leg trying to escape the attacker.

Israel's President Reuven Rivlin said: 'I am filled with sadness, as I received the terrible news of the murder of a young girl in the terror attack in Jerusalem.

'Our thoughts and prayers are with the family of the victim, and we wish all the injured a swift and full recovery.

'This week thousands have come through the ancient gates of Jerusalem, to celebrate the feasts of Passover and Easter throughout the city - while the security forces work to ensure the safety of the dear residents and visitors to the city. And so we will continue to do.

'Terror can never overcome us. Terror will never destroy our lives here.'

Hundreds of police were on the streets of Jerusalem in order to safeguard crowds of pilgrims who travel from all over the world for Easter celebrations and Passover

While religiously-motivated stabbing attacks in Jerusalem not uncommon, there has been a significant drop in violence over recent months

The area was cordoned off following the attack, which happened during Good Friday commemorations in the city

A UK Foreign Office Spokeswoman said: 'We are in touch with local authorities following an incident in Jerusalem on 14 April.'

Police had been on high alert for Passover when tens of thousands of Jews pray at the Western Wall inside the Old City and some visit the flashpoint Al-Aqsa mosque compound above it.

The compound, which is the third holiest site in Islam and the holiest site to Jews, who refer to it as the Temple Mount, is the source of constant tensions.

Jews are allowed to visit but not pray at the site.

Palestinian fears that Israel will seek to change those rules have been the source of repeated violence.

A wave of unrest which erupted in October 2015 has claimed the lives of 260 Palestinians, 41 Israelis, two Americans, one Jordanian, an Eritrean and a Sudanese, according to an AFP count.

Most of the Palestinians killed were carrying out knife, gun or car-ramming attacks, the Israeli authorities say.

Others were shot dead during protests or clashes, while some were killed in Israeli air strikes on the Gaza Strip.

The violence has greatly subsided in recent months.
