The One Love benefit concert to commemorate those affected by the Manchester suicide bombing is still set to take place in Britain despite the latest terror attacks in London.
The event was organised by singer Ariana Grande after 22 people died and 120 were injured following the Manchester leg of her Dangerous Woman world tour at the Manchester Arena last week.
Tickets starting at about $69 for the One Love concert were snapped up in six minutes. Those who attended her original show will receive free entry.
Greater Manchester Police Assistant Chief Constable Garry Shewan confirmed the One Love event will still go ahead despite the latest terror incident - the third in the UK in three months - "but with additional security in place".
In a statement he said an attack is "highly likely" and "that the threat level remains at severe".
He also urged ticket holders not to bring bags to the venue.
Fairfax Media has reached out to event organisers for comment.
However fans had already began camping out and security at the venue was increased before the latest London attacks on Saturday night.
The official Old Trafford Twitter account urged the 140,000 ticket holders to allow "extra time for travel and security procedures".
As of Sunday night, Australian Eastern Time, Channel Nine was still promoting the event which is set to be broadcast for Australian viewers on Monday evening.
Twitter will also be live streaming the event which will raise funds for the Red Cross.
A global community united.
Grande arrived back in Britain and visited victims of the Manchester attack in hospital just hours before seven people were killed by knife-welding terrorists in London.
Two Australians have also "directly affected" according to Prime Minister Malcolm Turnbull.
After news broke of the attacks on London Bridge and at Borough Market, Grande tweeted: "Praying for London".
