More than 200 people joined a march through north Leeds to campaign against the increase of gun crime in the city.
Pat Regan, who's son was shot dead, wants an end to gun crime
On Saturday they walked from Potternewton Park, Chapeltown, through Little London and Woodhouse.
The march finished at Hyde Park and passed the home of Richard Clark who was shot dead when he was asleep at his home last week.
Supporters of Mothers against Guns travelled to the city from all over the UK.
A Leeds mother, whose son was shot dead in Liverpool in December 2002, led the rally.
Pat Regan's other son was also shot and wounded in a Leeds nightclub.
Ms Regan, 49, needed help to come to terms with the gun-related crime that led to Danny's death.
Mothers Against Guns was the London-based group that gave her much-needed support and she set up her own organisation, Mothers Against Violence, Leeds.
She said: "We want to put a stop to the wave of gun crime and street violence and we demonstrated this by marching through Leeds.
"It's time to take responsibility and do all we can to make people sit up and listen."
The number of crimes involving firearms in West Yorkshire has increased in the last five years.
Eleven people were killed and 24 injured in shootings between 2000 and 2002.
