Around 1,000 protesters have been taking part in an anti-racism demonstration in Swansea city centre.
Mr Karim's body was flown back to Iraq this week
The event was organised following the death of an Iraqi Kurd in the city last month.
Kalan Kawa Karim, 29, was attacked outside a city centre pub in the early hours of 6 September.
A 26-year-old man has appeared in court charged with his murder.
More than 40 organisations were represented in the demonstration, which began at the city's Guild Hall.
The march stopped for a two-minute silence outside the Potters Wheel pub, where Mr Karim was attacked, and flowers were left on the railings.
The march had the backing of the local council, Wales TUC, and members of the Welsh assembly.
Swansea council leader Chris Holley and AMs Andrew Davies and Leanne Wood were among those addressing the demonstrators.
"The march in Swansea is making an important statement," said Ms Wood, who represents South Wales Central.
"To us on this march, racism is abhorrent - we will fight it, and we will defeat it."
Martin Chapman from the organising committee said he had been hoping for "a very big protest indeed".
And, he added : "Our call has reached all corners of Swansea, our supporters have been addressing school assemblies and leafleting in their streets and workplaces.
"Swansea will be united against racism."
