LONDON • Ms Christine Archibald, the first of seven victims killed in the London terror attack to be named, died in her fiance's arms after she was struck on London Bridge, the Evening Standard reported yesterday.

The 30-year-old Canadian from British Columbia was in London for the weekend with her fiance, Mr Tyler Ferguson.

She was a volunteer worker at a shelter for the homeless before she moved to Europe.

The couple had been living in the Netherlands for the past six months.

Another 18 of the 48 injured in last Saturday's attack remain in critical condition. Among them is an off-duty policeman who was stabbed in the face after rugby-tackling one of the three attackers.

Another British Transport Police officer is in stable condition after facing the attackers armed only with his baton.

French Foreign Minister Jean-Yves Le Drian confirmed that a 27-year-old Frenchman was among those killed, with another reported missing and seven other French nationals in hospital.

Australian Prime Minister Malcolm Turnbull revealed that four Australians were caught up in the attack, including Ms Candice Hedge and Mr Andrew Morrison, who were both stabbed and are recovering.

A woman from Brisbane reportedly became separated from her friends on London Bridge, according to The Sydney Morning Herald. Family and friends have made a social media plea to help find Ms Sara Zelenak, 21, who has not answered her phone since the attack.
