A Canadian woman killed in the London terror attack would have had 'no understanding of the callous cruelty that caused her death', her family said as they paid tribute to her.

Christine Archibald has been named as the Canadian national who died during Saturday's atrocity in London Bridge and Borough Market, one of seven killed and 21 critically injured. The Islamic State terror group has claimed responsibility for the terror attacks.

Ms Archibald's family said in a statement: 'We grieve the loss of our beautiful, loving daughter and sister. She had room in her heart for everyone and believed strongly that every person was to be valued and respected.

'She lived this belief, working in a shelter for the homeless until she moved to Europe to be with her fiance.

'She would have had no understanding of the callous cruelty that caused her death.

'Please honour her by making your community a better place. Volunteer your time and labour or donate to a homeless shelter. Tell them Chrissy sent you.'

Canadian Prime Minister Justin Trudeau said he was 'heartbroken' to learn of Ms Archibald's death.

Applauding the UK for its strength and resilience in the face of adversity, he said: 'These hateful acts do not deter us; they only strengthen our resolve.

'Canadians stand united with the British people. We will continue to work together with the United Kingdom and all our allies to fight terrorism and bring perpetrators to justice.'

On Sunday Prime Minister Theresa May visited some of the 48 people taken to hospitals across the capital after the attack.

A rest centre was also set up at London South Bank University where volunteers from the British Red Cross helped those affected, Southwark Council said.

Among the injured are:

• A British Transport Police (BTP) officer and an off-duty Metropolitan Police officer are in hospital with serious injuries but neither are believed to be in a life-threatening condition, Scotland Yard said. The BTP officer, who was on duty, was one of the first at the scene after he responded to calls for help from the public, the force said.

He suffered serious injuries when he was stabbed in the face, head and leg, wounds which BTP said are not thought to be life-threatening.

• New Zealander Oliver Dowling is reported to have been left in a coma after being stabbed in the face, neck and stomach.

Mr Dowling, 32, from Christchurch, is said to have had four hours of surgery for his injuries and is in an induced coma.

According to the Mirror, his sister Freddy Dowling said on Facebook: 'Doctors are very happy with how he's come out the other side. A massive thank to the University of London Hospital for their tireless efforts in helping my brother out.'

It was reported that his girlfriend, Marie Bondeville, was also injured.

• Sunday Express business editor Geoff Ho was left in intensive care after being stabbed in the throat when he tried to help a wounded bouncer.

Mr Ho was filmed being led away from the scene by a policeman, clutching his neck and with his shirt off.

Friend Isabelle Oderberg tweeted: 'We have found Geoff. He is in intensive care.' She told Melbourne newspaper The Age: 'He is actually a martial artist and I wouldn't be surprised if he would have stood up and been counted because he's just that type of person.'

• Candice Hedge is reported to be one of two Australians injured. The Courier Mail newspaper reported that she was stabbed in the neck while eating dinner with her boyfriend after finishing a shift at Elliot's restaurant in London Bridge.

The paper reported that the 31-year-old had her throat slashed after a man grabbed her from behind.

She reportedly wrote on Facebook: 'Hey everyone, just so you know I'm doing ok. Bit of pain but I will survive. Thanks for your thoughts and well wishes. Love to all.'

Jane Cummings, chief nursing officer for England and Sir Bruce Keogh, national medical director for NHS England, issued a joint statement, saying that - as with the Westminster Bridge and Manchester attacks - 'on each occasion we have seen both the worst and the best of humanity'.

It said: 'Last night, once again, the NHS and other emergency services reacted swiftly and heroically, going towards the danger to help the injured.

'Tried and tested emergency plans were activated, with London Ambulance Service on the scene within six minutes. NHS staff across the capital have also volunteered to work extra shifts and through the night to help the emergency response.

'As the medical director and chief nurse of the NHS in England we would like to put on record our gratitude and thanks to everyone for their tireless efforts and commitment in what has been a very difficult period.'

NHS England chief executive Simon Stevens said: 'The NHS has again shown that we are ready and able to respond to such attacks, thanks to the professionalism and bravery of our staff.

'While so far there has been minimal wider impact on services overall, we continue to keep the situation under close review as events unfold, and ask people in the capital to continue to use NHS services wisely.'
