Campaigners against the use of cluster bombs will participate in a protest march through Dublin this afternoon.
Hundreds of activists are expected to congregate with the Cluster Munitions Coalition at the Garden of Remembrance at noon.
They will then make their way through the city to show their support for the Cluster Munitions treaty negotiations, which are being hosted in Croke Park.
The Make It Happen rally is one of a series of events being held to highlight the conference. It will be followed by a free concert at The Academy, Middle Abbey Street.
