When asked if he would allow a CNN crew to videotape another interview with him, el-Amir said he would give his permission -- for a price of $5,000.

That money, he said, would not be kept for himself, but would be donated to someone to carry out another terror attack.

El-Amir said that $5,000 was about how much it would cost to finance another attack in London.

It is CNN policy not to pay people for interviews.
