Two mothers whose sons were stabbed to death in the same year, have taken their campaign for peace to a school in East London.
Jimmy Mizen and David Idowu were both murdered in 2008.
Their mothers have spent 100 days touring the capital speaking to young people about avoiding violent confrontations.
Their project will end with a concert on Sunday.
This report is from Ronke Phillips.
