Families of gun and knife crime victims are joining thousands of people on peace marches in London today - in a bid to stop people from carrying knives.

Two marches, from Kennington Park in south London and Caledonian Park in north London, will converge in Hyde Park.

Relatives of Damilola Taylor, killed in 2000, and Ben Kinsella, stabbed to death this year, are taking part.

The marches come exactly a week since 19-year-old football player, Oliver Kingonzila, was stabbed to death outside a Croydon nightclub.

And last night another man in his 20s was stabbed to death outside a club in Brixton.

The idea for the march was started on Facebook by two London women.
