This is shocking, but really what did the politicians who let in large numbers of people from countries far more violent than our own, such as Somalia and Jamaica, expect? Did they imagine that there is something special about London water or air that accounts for a difference in behaviour between Middlesex and Mogadishu?

Jim and Richard of London. You are both absolutely right!!

This is only the list of teens killed by teens. How long is the list of other citizens also killed by teenagers this year?

It is awfull to hear about youths doeing things to harm others. I am a youth myself at 17. Now it is skary to walk home from work on my own and it is scary to go anywhere on my own, because of incedents that i see in the news. I am corcious when i am left on my own in the day. I thinck a lot of people who are my age feel the same way. The way to tackle the violence on the streets is to make the age rate of a violent fillm higher and the same with video games as it think that some of the violence comes from these as youths now think it is cool to carry a knife or a gun and be sent to prison.Whereas the reality is that it is not and it will ruin there lives. I thinck it is the parents responcerbility to look after there child and stop them fron seeing things that can effect the way they act.

I think I'm right in saying everyone of the victims is non white and everyone of the murderers/suspects is non white. We can't really see it as a breakdown of Britsh society therefore, when you let in a diaspora of nationalities then this is likely to happen. Black society in particular has to get a grip and not let their teenagers run wild. Their reverence for needing 'respect' in every situation and general chip on the shoulder mentality is at the cause of this plague of needless deaths.

Jim, London,

Talk about the Emperor having no clothes!! This is a racial problem.

Please stop asking the police to do the parents job.
Make parents accountable for their own children
Parents should be held accountable until their child reaches 16

Peter Stisted, Sark, channel islands

Yes, Emma. Eleven teenage murders in a three month period would be seen as an improvement in a country with more than 300ml people. Is it that bad in Minneapolis, which probably only has a tenth of London's population? To put it in perspective, it's more than one 13-19 year old person (actually male) being murdered every nine days. May those poor souls rest in peace.

Noel, London,

Gangland killlings is not a question of whose politics you follow but what is going wrong in society and epsecially with our young poeple. You can have as many laws as you like banning weapons. But it comes down to parents in the end to know what their children are doing and who they are associating with.

In respect of the law, I think a mandatory sentence for carrying a offensive weapon should be considered, instead of a maximum sentence. In addition to more stop and searches.

Michael GC, London, UK

Such a tragic waste of young lives, we need to really tackle the route cause, banning everything won't help, but more discipline and respect may help to build a society where people feel a desire to belong and less likely to isolate themselves into gangs.

Responsibility lies with parents and educaters from the birth of children to raise them to feel worthwhile and have a sense of belonging, this can only be done in an environment of discipline and love.

It's ok to control children and remember they are not adults and need to be guided to make positive choices. I feel the liberal attitudes that have taken a hold where noone can actually admonish a child for fear of prosecution, are ruining youngsters lives. Children need clear boundaries and controls set by loving family and school communities, that's how they know they belong and are cared about. Without these elements our children are failed and gang culture can thrive.
I hope its not too late, no more should die in this way

Labour's crime policy is just not working. Whatever "tough on crime" means it is just not working!

I know it is shocking in the UK and of course one is very sad at any needless violence but here in the US, 11 teenage deaths in three months would be a big improvement!

Emma, Minneapolis, MN, USA

Time to ban knives now.

Perhaps media and government should stop blaming the tools of violence, and instead start to have a look at the society that produces so many people with no respect for human life.

Tim, Colorado Springs, USA

The photo at the top shows the problem. Kids trying to be gangsters.

I don't know what we're going to do about this problem. Too many disaffected youth. Too many people looking around and seeing other people with good jobs, some money, cars, prospects etc etc. They want all these things, but rather than work for them, they just blame other people (or society in general) for not having them.

I think part of the problem is a lack of work ethic and sense of self-respect among todays young people. But this is symptomatic of a much wider problem. We need to have a society where people feel valued, where people feel their is a point, otherwise we cannot expect people to have any optimism.

Banning knives is not possible. But doing something to improve the opportunities available to members of or society certainly is.

Mike, Beijing, China

1) BAN Knives
2) Ban Violent Games
3) Ban Rap music that glorifies such ruthless gang culture.

Send tough EX. army officers into the school to educate young kids about the importance of tolerance, respect and value of human life.

Shi, London, London

So can we now OUTLAW knives like they did guns.

Stupid. (people kill people anyway they can)

Lee, Seattle, USA

Two knife murders in Birmingham this week. A regular crime here, completely out of control. London does not have a monopoly on youth violence.

Gordon, Birmingham, England

I cant belive this is going on in our multicultural and diverse capital. Give me a shout when the troops are on the streets and then I might come down for a visit in safety.
