Cardinal Vincent Nichols, along with several religious leaders, has condemned the attack on Muslims in London this week.
A white van was driven into a group of people who had just left the Muslim Welfare House in Finsbury Park, killing one man and injuring up to 10.
A 47-year-old man was detained by people at the scene, and was later arrested by police.
“Together with people all over this country, I am appalled at the deliberate attack on people leaving their late-night prayers, at the end of their day of fasting, at the mosque in Finsbury Park,” said Cardinal Nichols.
“Violence breeds violence. Hatred breeds hatred. Every one of us must repudiate hatred and violence from our words and actions.
“We must all be builders of understanding, compassion and peace, day by day, in our homes, our work and our communities. That is the only way,” he added.
The Archbishop of Canterbury said the attack was “appalling” and was an “attack on us all and the culture and values of our country”.
In a statement posted on twitter he said: “At a time when we are all grieving the loss of so many precious people in London and Manchester, this brutal attack can only compound the trauma.”
Religious leaders across Europe and the UK spoke out against the vicious attack on worshippers at the London mosque – which has previously been a target for anti-Muslim acts.
The Muslim Council of Britain urged calm among worshippers, adding that they want action taken to tackle the “hugely worrying growth of Islamophobia”.
“Many will feel terrorised, no doubt be angry and saddened by what has taken place tonight. We urge calm as the investigation establishes the full facts, and in these last days of Ramadan, pray for those affected and for justice,” said Harun Khan, the group’s General Secretary.
The Sikh Federation UK said that hate and terror must be “stamped out”, by confronting those who promote ideologies based on those principles.
The President of the European Jewish Congress stated: “This is an unconscionable attack on Muslim worshippers during their holy month of Ramadan.”
“An attack on one religion is an attack on all religions and all people and faiths must stand together against terror.”
President of the congress, Dr Moshe Kantor, added they condemned the attack, and its “attempt to escalate tensions in the UK”.
Witnesses said the Imam from the mosque protected the driver from angry members of the public.
