'I was waiting for the smoke to fill my lungs or for flames to become visible...waiting to die'

Selection of quotes in the aftermath of the bombing.

"I WAS on a train. It stopped at Kings Cross, then went into the tunnel. We heard an incredible bang and our ears popped as if they were pricked with a thousand needles. Then within seconds the smoke began billowing in through the carriages as the lights went low. At this point I was waiting either for the smoke to fill my lungs or for the flames to become visible... waiting to die."

"It's business as usual today and we refuse to let the terrorists win. We defied Hitler and the IRA, do they think we will be rocked by this cowardly act? We will not."

Alex Saunders, Russell Square

"I already went through this. I lived five minutes from the station in Madrid. I've seen 100 broken families in Madrid, many people still suffer deep inside from what happened in Madrid. Now, here again, I work in the city and in that sad morning I passed the Moorgate station earlier than usual. Lucky me, but what about those who didn't make it?

"As a French Muslim I am deeply upset and ashamed by this barbaric attack on London. It is high time now for us Muslims to stand against those who have taken our religion hostage and show the world that we have nothing to do with terror."

Jasmine, Paris

"We will stick together... to fight these dreadful people who can do these inhuman uncivilised acts. Australia will be always by your side to fight for freedom."
