A 17-year-old girl has died in the latest of a series of violent killings in London.

Police were called to reports of a shooting in Tottenham, north London, at 9.35pm on Monday.

Officers found the teenage girl with a gunshot wound in Chalgrove Road, a residential street near Northumberland Park station.

"Despite the best efforts of the London Ambulance Service, she was pronounced dead at the scene at 10.43pm," a Scotland Yard spokeswoman said.

"Her next of kin are aware and a crime scene is in place. No arrests have been made at this stage."

Neighbours said they heard gunshots at around 9.30pm on Monday. One witness, who works in a nearby shop, said he heard three bangs which sounded like fireworks.

He said he saw the victim sat with friends following the shooting before police cars and ambulances arrived. He also saw blood on the right side of the 17-year-old's chest.

Another neighbour described the murder as "very sad". She said: "I heard the bangs because I sleep in the front room. I thought it was a bomb.

"It's not nice - so many drugs, stabbings, cycles up and down - no respect for people any more."

Less than half an hour after the alarm was first raised in Tottenham, police were alerted to another shooting around three miles away in east London which left a 16-year-old boy fighting for life.

Scotland Yard said it was called to reports of gunfire in Markhouse Road in Walthamstow at around 10pm.

On arrival they found two young victims suffering from gun shot and knife wounds.

The spokeswoman said: "A 16-year-old boy was found with gun shot injuries. He has been taken to an east London hospital where he remains in a critical condition.

"A second victim, aged 15, has been taken to an east London hospital with stab injuries. We await an update on his condition."

The spokeswoman said it was too early to say if any links between the attacks were being investigated.

Local Labour MP Stella Creasy tweeted: "Walthamstow - can confirm tonight we have had another serious incident involving shooting and stabbing.

"Appreciate this is very distressing- I will share more information as and when have it from official sources as only want to share what is confirmed."

The incidents come amid concerns over rising violent crime in the capital.

On Sunday a 20-year-old man became the 31st victim of knife crime in London so far this year. He was fatally stabbed moments after leaving a bar in Wandsworth and died in the street.

On Thursday the family of Abraham Badru, 26, who was shot dead down in Hackney, east London on March 25 warned that "gun culture is becoming rampant in our community".

A new report recently showed London's murder rate had overtaken New York City's for the first time ever. February marked the first month the UK capital saw more murders than New York, with 15 dead (nine aged 30 or younger).

According to the report in the Sunday Times, London also suffered 22 fatal stabbings and shootings in March, higher than the 21 in the Big Apple. Both cities have similarly sized populations of around 8.5m people.

New York City's murder rate has decreased by around 87 per cent since the 1990s. Meanwhile, London's has grown by nearly 40 per cent in just three years, not including deaths caused by terrorist attacks.
