I was working in the information booth on the island. We were informed by radio of a bombing in Oslo, so we gathered all 700 people on the island together to tell them.

A couple of minutes later we got a phone call to say one policeman was coming on to the shore to see us.

I went to the coffee shop to get supplies for everyone. I then heard gun shots and could see people running. As they were running, they were shot in the back. People were falling dead right in front of me.

I ran through the campus to the tent area. I saw the gunman - two people started to talk to him and two seconds later they were both shot.

He was wearing a black uniform with red edges. He looked like a Nazi, with his police-like uniform and hair.

The gunman was very sure, calm and controlled. He looked like he knew what he was doing. He screamed at us that we would all die.

We started to run down to the water, people had already undressed and started swimming. I thought I didn't have enough time to take off my clothes, so I started swimming in the rain, in my clothes and big boots.

I went for about 150 metres but the lake is about 800 metres long. I realised I wouldn't make it so I turned back.

I saw him standing 10 metres from me, shooting at people who were swimming. He aimed his machine gun at me and I screamed at him, No please no, don't do it. I don't know if he listened to me but he spared me.

He came back an hour later. I was with other survivors and we were lying down and hiding behind the trees and rocks. We were freezing in out wet clothes.

The shooting started again and people were falling on top of me, on my legs and falling into the water - that's when many people died. I just had to shield myself behind them, praying he wouldn't see me.

Then he came closer, I could feel his breath, I could feel his boots, I could feel the warmth of the barrel. But I didn't move, and that's what saved my life.
