A minute's silence will be observed in Wales today on the 50th anniversary of the Aberfan disaster.
Demo Planned Ahead Of NATO Summit
Protestors - who are planning to demonstrate ahead of the NATO summit - say Wales won't benefit from hosting it.
World leaders, including Barack Obama, will be at the conference at the Celtic Manor in Newport.
The two day conference will take place on the 4th and 5th of September.
It's argued having world leaders in Newport will put the spotlight on Wales - boosting our profile but some campaigners wish the conference wasn't coming here at all.
Jonny is part of the Anarchist Action Network.
They are planning a march in the run-up to the conference: "They're not going to change their minds because of a few protestors but if we can show people that there is an alternative because the NATO system has failed."
First Minister Carwyn Jones has already said the Nato Summit will be the largest international event ever staged in Wales.
It'll be covered by the world's media - giving us global exposure - but protestors say the conference won't bring the benefits that are being promised.
Jonny told Heart: "The Ryder Cup is a big golf tournament which had a lot of similar coverage - absolutely it will not benefit the people of Newport. Nato will come and go."
He added their protest will be peaceful and it's important people have the chance to say what they think.
"I personally will try and get as close to the Celtic Manor as possible.
"I'm not sure that everybody agrees with that but I think we need to make a very visual and verbal denunciation of this".
Gwent Police tells Heart they'll work with protest groups to make sure any demonstrations are lawful.
