My brother Yoram spotted him first, but a split second later I saw him too. He was small, like a child -- he can't have been more than 17 -- and he was wearing a big smile.
It was a sinister rather than a happy smile, the smile of someone whose mind has been skewed by drugs.
As he reached the cafe door, I could see he was hiding something underneath his shirt.
Yoram shouted, but it was too late. There was an ear-splitting noise and a blinding light, then darkness, silence and a smell I cannot describe: the reek of shredded, burning flesh.
I had been standing at the front of the cafe, behind a pillar. Yoram had been outside by one of the pavement tables.
As I looked up, the floor-to-ceiling glass that separated us was cascading like a waterfall. I looked down. Incredibly, thanks to the pillar, I appeared to be unharmed.
Then I looked right and left and, through dense, black smoke, I saw things that no one should see. All around me were people who were horribly mutilated, without hands, arms, legs.
The body of one of the customers, a doctor, was in three pieces and on fire.
Alon, the cafe security guard, a young man of 21, was charcoaled with burns.
As I stepped sideways, desperately looking for Yoram, a man reached out to me. He had no legs and could not speak, but his eyes were saying "please help me". As I leant down to touch him, he took his last breath....
It was about 11.15pm when the suicide bomber approached.
How did we know what he was? I can only put it down to instinct. I heard Yoram call to Alon, "There's a bomber".
Alon, who was sitting by the entrance, pushed him away, and in that instant the bomb exploded.
The front of the cafe took the full force, as did a car outside, which belonged to the doctor. Inside was his daughter, who was going to be married the next day.
They say if you get caught up in a bombing, you shouldn't look around you because what you see is so terrible you will never forget it. But I had to look. I needed to find my brother.
It was 20 minutes before the police could tell me he was alive -- he had been thrown 200m by the blast.
