The number of murders being investigated by Scotland Yard in London has surpassed New York for the first time, according to latest figures released for the months of February and March.
Fifteen people were murdered in the UK capital in February and 23 in March compared with 14 and 21 respectively in New York, a city with a similar population size.
For 2018 so far, there have been 46 murders in London, with 31 as a result of knife attacks. Murder rates in London had seen a steady decrease from 206 in 2003 to 94 in 2014 but the figure rose to 119 in 2015 and 116 last year.
"London remains one of the safest cities in the world. One murder is one too many, and we are working hard with our partners to understand the increase and what we can all do to prevent these tragedies from happening in the first place," a Metropolitan Police spokesperson said.
Croydon Central MP Sarah Jones, who chairs the UK's All-Party Parliamentary Group (APPG) on Knife Crime, told the BBC that London could learn from New York in how to reduce violent crime.
"New York has been able to bring down serious violence through a public health approach. We need a proper strategy that looks at all of the issues. Knife crime and violent crime acts like an epidemic, so you need to go in at the source to cut it off and then you need to inoculate the future young people against it, she said.
"Going in at source means major intervention work with youth workers, inoculating means going into schools, changing the social norms, educating kids, teaching them what it is to be a man, teaching them how they don't need to carry knives," she added.
