London Mayor Sadiq Khan says he will not deploy army troops on the streets of the capital following recent shootings and stabbings.
Mr Khan is under increased pressure to find a resolution to the issue after a teenager was fatally shot in south-east London over the weekend.
Khan told ITV London: "We don't want the army on the streets of London.
"We are doing what we can with the resources we have to keep our city as safe as we can from all the threats we face: terrorism, serious violent crime and other issues that London face as well."
Rhyhiem Ainsworth Barton was fatally gunned down in Southwark on Saturday.
The 17-year-old rapper and aspiring architect had "so much potential", his mother said as she tearfully told of her "handsome boy".
Rhyhiem's death is the latest in a spate of violent crimes in the capital, as police investigate more than 60 alleged murders so far this year.
Another teenager was shot in the head in Wealdstone, too.
