“It’s very sadly becoming predictable.”
And another one said: “Hoping everyone is ok. Such a beautiful day – shocking that for some it has started this way.”
The horrific event is the latest violent attack to take place in the capital this year.
Just hours earlier this morning, a 30-year-old man was found dead after being involved in a fight outside the Greenford Tube station.
And yesterday the Metropolitan Police released the image of a man wanted in connection with another stabbing, which took place on June 20.
At least 46 people have been fatally stabbed in London since the beginning of the year.
And a total 1,296 stabbings have taken place between January and April, according to statistics released by the Met Police.
This surge has seen London overtaking the homicide rate of New York, which has the same population number, for the first time in history.

The rise of violent crime in London has been blamed partly on an excessive supply of cocaine in the country.
Earlier this year, Met Police Commissioner Cressida Dick also accused some music videos saying they “glamourise” violence.
London Mayor Sadiq Khan has accepted responsibility for the dramatic increase of violence as the capital’s crime commissioner, but blamed the rise on cuts to youth services.
He said: “I’m the Mayor of London, I’m the Police and Crime Commissioner – I accept responsibility for what happens in our city.
“Security is the biggest concern I have, it’s the one thing that keeps me up at night – whether it’s terrorism threats, whether it’s the surge in serious violent crime.”

But he urged the government to reverse their police cuts to help with the crime surge.
He added: “We’ve seen in Liverpool, Manchester, Cardiff, shootings in daylight hours where teenagers have lost their lives.
“Over the past three or four years, we’ve seen an increase in violent crime across the country.
“These are national problems which need national solutions.”

Victoria Atkins urged parents to ‘count their knives’ to help the government fight the crime
Home Office Minister Victoria Atkins, who has the special responsibility for tackling the rising number of knife offences, urged parents to “look in your kitchen drawer and count your knives and make sure you know where the knives are” to help the government fight crime.
The minister also hit out at social media companies, who she believes host on their platforms videos which insight violence.
She expressed her shock at the video, saying: “I’ve seen some of these videos, these videos have the name of the people or the gangs that people want to murder”.
YouTube said to have removed 30 videos inciting violence following requests from the Met Police in the last two years.
