There is a particularly serious issue of teens killing each other in London. It is often related to youth-gang criminality. The following BBC News article excerpt is an example of comments made by parents who have sadly lost their children that way in London:
Hawa Haragakiza, Tamim's mother, said: "Every single day I have to think 'oh, he's not here anymore'. It's really hard and I don't even know whether I'll get better."
Teenagers being killed has become "a normal thing" in London, she said.
"I feel for them," she added. "These kids had futures, and their parents had so much expectation for their kids.
"And someone decided to just wake up one day and says I'm going to kill him.
"It looks normal for another kid to die and I'm really scared about the future here."
