He stood up to Sudan's tyrannical government. Soldiers shot him dead

As Sudanese soldiers fire live rounds at unarmed protesters, a young man stands his ground, then moves forward, berating the soldiers for firing at civilians, telling them they should be ashamed.

Moments later, he lies dying on the ground, shot three times. The picture of Abdulazim Abubakr went viral in Sudan.

A university graduate and just 25 years old, he embodied the spirit of the youth-led revolution currently under way in Sudan. He, like many others, died standing up to the tyrannical government of Omar al Bashir.

The dictator has gone, but the revolution isn't done.

Abdulazim lived in a mud-bricked series of rooms on a dusty street in the city of Omdurman, across the River Nile from Khartoum, with his brother and sister and their parents.

The revolution, now famous around the world, started in places such as this at the end of last year.

Small, scattered uprisings eventually morphed into an enormous street protest at the heart of the government's power base in the capital.

A mural of Abdulazim is painted on a wall outside the family home. Next to it a quote, his last post on social media: "We are tired my friend, but nobody can afford to lay down during battle."

We drove out to meet the family. They have never spoken about his death until now.

Originally from Darfur, the family moved to Khartoum for the children's education and for work. The education, they got. Work and money however was much harder to find.

This family, like so many in the country, are dreadfully poor. The revolutionary movement here was born in poverty. In many ways it is why it happened.

Abdulazim's brother, Omar, 28, and his cousin, Mustafa, 34, ushered us through a gate and past a series of rooms to another small room with just two beds inside, where we were introduced to his sister Fatma, a 21-year-old university student.

They have many photos and a video of their brother's dying moments. A video they have never seen to the end.

I asked Fatma what it was like when she first realised that her brother had been shot. She knew he was on the street, but they only found out what had happened as his body was brought home.

"It was a huge shock, I've never experienced anything like this," she told me through tears. "I felt completely alone because all my family is here and suddenly my brother dies and they bring him to me. It was a terrible feeling, heartbreaking."

I asked her what she would say to him now, after all the advances that have been made by the revolution in recent days.

"I would say 'God bless your soul, and I am very proud to be your sister'. As my father would say, he made us proud in life and in death. I miss him dearly."

Many of the people we have spoken to at the main protest site in Khartoum, who have lost loved ones to soldiers' bullets or through torture, are demanding retribution. Here they call it "blood for blood".

I asked Omar if he agreed with that and wanted the same.

"Sudan deserves much more than this," he replied. "It wasn't only Abdulazim, there are thousands of Abdulazims. They all died so that Sudan can be liberated and become good again.

"Everyone would want to avenge their brother's death, we want retribution, but we also want a better Sudan."

All of the family's youngest members took to the streets in protest, but they never told each other until this interview.

Incredibly, they all kept it a secret from each other, apart from Abdulazim, who posted pictures and video on social media.

In a moment of hilarity, Omar told his sister off.

"If I had known what she was doing, I would never have let her out," he said laughing.

The point is that in this revolution, young men and women have played an equal part. They have torn up the old rules.

While they remain heartbroken, none of them regret what happened to Abdulazim.

"We wish those who died were here with us to witness the changes that are happening," cousin Mustafa said. "But it is God's will that they are not here. What happened in Sudan was worth the sacrifice of lives - our homeland is precious and we love Sudan. It was necessary for people to sacrifice everything."

The revolution is not yet won, but these men and women, like millions of others believe it is near. It is within the grasp of those who lived.
