The cousin of the British Rabbi killed in the synagogue attack in Jerusalem said she was very privileged to have known him.
In an interview with ITV News Michelle Hirschfield described her cousin as "caring and peaceful", and said the whole community was shell-shocked by his senseless murder.
The family of Rabbi Avraham Shmuel Goldberg said they could not understand how the men that killed him could have such a disregard for human life.
Mr Goldberg, who was born in Liverpool and holds dual British-Israeli citizenship, was among four people killed after militants stormed a synagogue in Jerusalem. In a statement to ITV News, his immediate family said:
It's a massive waste of life, we cannot understand how people have no value for human life.
The British man who was killed during the Jerusalem synagogue attack "only wanted peace", his relatives said.
Avraham Shmuel Goldberg was one of four people murdered when two militants stormed the building and attacked worshippers with knives, axes and guns before being shot by police.
Mr Goldberg was 68 and was married with six children, as well as several grandchildren and great grandchildren.
His cousin Michelle Hirschfield told the BBC:
He was a peaceful man, not politically involved. He only wanted peace.
It is thought Mr Goldberg moved to Israel from Golders Green, north London, in the early 1990s. He held dual British-Israeli citizenship.
US President Obama has condemned the attack on a synagogue in Jerusalem where three US citizens died as a terrorist act, saying "there is and can be no justification against attacks against innocent civilians". He called for Israeli and Palestinian leaders and citizens to work together to lower tensions.
I strongly condemn today’s terrorist attack on worshipers at a synagogue in Jerusalem, which killed four innocent people, including U.S. citizens Aryeh Kupinsky, Cary William Levine, and Mosheh Twersky, and injured several more.
There is and can be no justification for such attacks against innocent civilians. The thoughts and prayers of the American people are with the victims and families of all those who were killed and injured in this horrific attack and in other recent violence.
At this sensitive moment in Jerusalem, it is all the more important for Israeli and Palestinian leaders and ordinary citizens to work cooperatively together to lower tensions, reject violence, and seek a path forward towards peace
Dozens of police officers clashed with Palestinians in the Jabal Mukaber area of east Jerusalem as they raided homes and made several arrests.
The raids come as Israeli police named cousins Ghassan and Udai Abu Jamal, from Jabal Mukaber, as being responsible for the synagogue attack which killed four people, including one British-Israeli.
Police fired tear gas as residents of the neighbourhood threw stones. According to witnesses Israeli policemen forced their way into homes to conduct searches and several arrests were made.
The Popular Front for the Liberation of Palestine, a militant group, said the cousins were its members, but did not specify whether they had instructed the cousins to carry out the attack.
Palestinian President Mahmoud Abbas held a press conference today to condemn the attack on the synagogue in Jerusalem today, but also took the opportunity to speak out against "Israeli aggression".
While we condemn this action we also condemn the Israeli aggression on the holy sites, like burning mosques and churches.
All of these actions are not helping the Palestinian and Israeli interests to establish a Palestinian state and live side by side in peace.
We call for a complete cessation in the violence in order to continue the political path that leads to peace in the Middle East.
Israeli police and the US State Department has confirmed one of the victims of today's attack at a synagogue in Jerusalem was Rabbi Mosheh Twersky, who taught at a seminary in the city.
Twersky was from a Hassidic line and grandson of Joseph Soloveitchik, a renowned Boston rabbi who died in 1993.
The two other American victims, Aryeh Kupinsky and Cary William Levine, also held dual American-Israeli nationality.
The fourth victim of the raid was British-Israeli Avraham Shmuel Goldberg.
The funerals of three of the four victims killed in an attack at a Jerusalem synagogue are taking place today.
Among them was British-Israeli dual national Avraham Shmuel Goldberg, and two of three American-Israelis also targeted in today's attack.
Speaking from the scene, ITV News Middle East correspondent Geraint Vincent said the atmosphere in the city had changed from one of shock and anger to one of grief.
He said earlier today, people had been chanting and demanding the death of the four Jewish men be avenged, and said political leaders were now fearing a series of "tit-for-tat" attacks.
Three Americans were also killed in an attack at a synagogue in Jerusalem which left a British-Israeli national dead, The Associated Press reports.
The British-born Israeli has been named by police in the country as Avraham Shmuel Goldberg.
