The Labour Party’s home affairs spokeswoman was kept out of the spotlight, with the party instead favouring shadow foreign secretary Emily Thornberry, who conducted a series of interviews with reporters.
Seven people were killed and 48 more injured when three terrorists launched a sick attack on London Bridge and Borough Market on Saturday night.
British Twitter users voiced their concern over Ms Abbott’s absence because she could be in charge of the United Kingdom’s security after the General Election on June 8.
One user wrote: “I’m somewhat concerned that with only three days till voting, shadow home secretary is nowhere to be seen and silent on the terror attack.”

A second added: “Jeremy Corbyn, we are really concerned that nobody has heard from Diane Abbott since the terror attacks. Surely you’ve not gagged her?”
Another said: “If Diane Abbott is a future home secretary why have Labour kept her out of the public view. They are concerned she will do another car crash interview.”
Ms Thornberry, appearing on Talkradio, was asked about the whereabouts of Ms Abbott during an interview about Friday night’s attack.
The shadow foreign secretary said she didn’t know where her colleague was, but suggested that terrorism is part of every shadow minister’s brief.

A Twitter user wrote: “Diane Abbott is that useless that Emily Thornberry is sent to interview over domestic issues!”
Another said: “Emily Thornberry is struggling to explain why Diane Abbott is not commenting on the London terror attack.”
In a separate interview on BBC Radio’s 5Live, Ms Thornberry came under criticism after she suggested Britain’s Muslim communities cannot be expected to police itself.
She claimed Labour would ensure the anti-radicalisation programme Prevent worked “as well as it possibly can” to stop further attacks in Britain.
When challenged over 3,000 so-called jihadis living in the country and potentially alienating the Muslim community, Ms Thornberry said: “No, I think that we’ve heard, haven’t we, in relation to the Manchester murderers and the London murderers that certainly it has been suggested that there were attempts made to contact the authorities and say there were concerns about particular individuals.

“We can’t be expecting the Muslim community in this country to police itself, it has to work with the authorities so we need to make sure there are better connections, and trusted connections – that does take sensitive work and focus.”
One Twitter user described Jeremy Corbyn’s shadow cabinet as “dangerous”, as the shadow foreign secretary was slammed over her defence of the Labour leaders anti-terror policies.
He wrote: “Emily Thornberry on 5Live yet again defended Corbyn’s past policies, this time on anti-terror.
“The man is a danger to us all.”
A second added: “More police officers more important than targeting UK jihadis it seems. Flawless logic.”
