'I have to do this thing for our future'

"Sweetheart, not long to go now. And I'm going to really, really miss you a lot.

"I'm thinking about it already. Look, I absolutely love you to bits and you have been the happiest thing in my life. You and your mum, absolutely brilliant.

"I don't know what else to say. I just wish I could have been part of your life, especially these growing up – these next months, they're really special with you learning to walk and things.

"I just so much wanted to be with you but I have to do this thing for our future and it will be for the best, inshallah, in the long run.

"That's the most important thing.

"You make plenty of Dua for you guys and you've got loads of people to look after you and keep an eye on you.

"But most importantly I entrust you to Allah and let Allah take care of you.

"And I'm doing what I'm doing for the sake of Islam, not, you know, it's not for materialist or worldly benefits."

The video shows a doting young father, kissing the head of his brown-eyed two-year-old baby girl, nestling in his arms in a pink dress. She is reaching for the camera with her chubby hands and kicking her legs with happiness. Her smiling 'uncles' laugh as the father records his farewell on a home-made video. One 'uncle picks her up, doffs his cap and places it on the baby's head, another flexes his biceps and grins for the camera.

'What's your words of wisdom?', the father asks the men.

' A few words of wisdom - kill everyone there is', another man replies. Smiling broadly.

I could barely make it out, but there it was. The video of a man going to Pakistan ,who at that point, in November 2004, did not expect to come back. The tapes were handed over by his wife to a friend, who passed it to the police after four bombs killed 52 innocent passengers and injured hundreds more.

The loving father was Mohammed Siddique Khan, the 'uncles', his fellow-suicide-bombers Hasib Hussein and Shehzad Tanweer. The other uncle, his alleged close friend and conspirator Wahid Ali.

I watched the video in an annexe to Kingston Crown Court with some of the bereaved families and it made me want to weep, because there was such love, and such hate, which became such murderous poison, as he cradled a sweet pink rose of a child, amongst his laughing friends.

It was one of the last videos shown after a day of the CPS's careful presentation in their opening speeches. We saw CCTV footage - never seen in public before - of the 7/7 bombers sky blue Nissan Micra, hired from a Leeds car rental firm, leaving for London in the early hours of 7 July 2005, departing from 18 Alexander Grove, (the bomb factory address.)

Stopping at Woodall Services on the westbound M1 at 4.53am, Shehzad Tanweer in white trousers and white branded sports top with a black coat stopping to put petrol in at 4.51am, then entering the petrol station shop at 4.54am, returning with a carrier bag of goods, ( sandwiches and snacks) - and the car driving away at 5.14am.

Then, fellow-bomber Germaine Lindsey, who bombed my train and killed 26 fellow-passengers, waiting at Luton station. Walking from the car park where he parked his burgundy Fiat Bravo near to the entrance of Luton station at 6.41am. Moving about, sometimes off-camera in the ticket hall for three minutes. Walking to the exit again, his mobile in his left hand, at 6.44am. Getting back in his car and repositioning the Fiat nearer the ticket hall.

At 6.51am the Micra arriving containing his three companions, his fellow shahid - and parking next to the Fiat in the wet, puddly car park. At 6.53 there is movement between the two vehicles and the boot is opened and closed several times. At 7.14am Lindsey goes back into the ticket hall, a minute later, he returns to the group and at 7.16am the men put on their rucksacks and leave the car park for the station. At 7.25 the men are on the concourse, getting onto a Thameslink train bound for London. At 8.25am the men arrive at Kings Cross station, move to the London Underground network and separate at 8.26am.

They apparently believe that the next time they see each other will be less than an hour later in the gardens of Paradise.

Next we saw footage of the exploded train at Edgware Rd. We saw footage of the Aldgate train explosion, seen from the Liverpool St platform it departed from. Passengers crouching in shock, smoke pluming and billowing, two police officers going to the platform. Then the same platform again from a different angle. Then stills of the exploded carriage are shown. Torn apart, as lives of the living and dead were torn apart.

Next, we are shown stills of the Piccadilly line train, the one I was on. I have seen the pictures of the inside of my carriage, but these were from the outside, and they were worse, because I could see how close I was to the bomb, and the debris on the tracks. Not bodies, just clothes. They had carried the broken bodies away. But I saw what I thought were clothes on the day; they were not piles of clothes, they were people. I remembered.

Then we saw the CCTV of teenager Hasib Hussein, who did not detonate his bomb at 8.50/8.51am as his 'brothers' had done.

We heard how witnesses saw Hussein waiting on a bench on the Northern line platform at 8.45am, exiting the Northern/Victoria line escalator,

We then saw CCTV of him exiting Kings Cross Underground station at 8.54am, then heading through Boots at 8.59am. Moving across the main railway station concourse at 9am, bending over outside next door shop WH Smiths where I have stopped so many times, and fiddling with his rucksack. Making a purchase, something that looks like a battery at 9.04am. (The woman serving him reaches down to the side of where the cigarettes are sold and hands him a small item; from memory, that is exactly where the batteries are. I cannot see what else it could be)

At 9.05, Hussein leaves the King's Cross concourse, heading out of the railway station, and by 9.07am he is out of the station, crossing York Way and heading into McDonalds at 9.15am , as rain falls. Two minutes later he is out of McDonalds and heading up Gray's Inn Rd, towards Euston Rd, making calls on his mobile. By 9.20am he is in Euston Rd, having slipped on a pair of sunglasses.

He took the 91 bus to Euston Square, where the driver told the passengers to get off. Hussein boards the number 30 bus, heading for Tavistock Square.

Then we saw CCTV footage of the exploding bus shot from inside the reception of the British Medical Association. The man at the desk, a woman in reception, ducking for cover, as the explosion happens, then the receptionist man going to the door, where the red bus, torn apart is smoking outside. Thirteen more people are dead. Next we saw the footage from the bus in front of the No.30, the passengers jerking in shock as the bus explodes behind them.

For two years, conspiracy theorists have been saying there is no CCTV of the 77/ bombers save one grainy shot, (which they say is faked). There is, I have seen it played in a public court. They could have seen it too, if they had bothered to come. It is real, it was always real. Why do they peddle their lies about it?

The defence are not contesting it; they are not contesting these facts - that Khan, Tanweer, Lindsey and Hussein set off with home made bombs and met up at Luton and took the bombs in rucksacks to London where they split up and detonated them as you have heard and people have seen. And felt, and died as a result of them.

I hope that this will be an end to this filthy lie. That the 7/7 bombers did not do it. I am weary of these lies after over two years of hearing them and seeing them spread on the internet.

And we saw many other things presented by the prosecution, which the court was told helped to show the 'mindset' of the men who claim that their friendship with the 7/7 bombers was innocent, their reconnaissance trip to London a tourist trip, one of their number's association with a known terrorist merely a coincidence, their trips to Pakistan ...more on that next week.

The trial continues on Monday. I will be there.

There is more I could write, but I am so tired, and this is long enough for now.
