Much of the revolutionary street-art done by Sudanese anti-government protesters were destroyed. With a few of the photographs that were left and a few other paintings, an exhibition was conducted in London.

At a central London university space turned into a temporary gallery the work brought in a lot of students and art lovers.

'It's all gone now'

Jumana Amir, 20, a student in Cardiff, Wales who came to Britain from Sudan aged three, travelled to London to see the 30 or so images on display for two days at SOAS, which specialises in the study of Asia, Africa and the Middle East.

She was already familiar with some of the artworks after glimpsing them in videos of the sit-in protests shared by relatives.

"Unfortunately it's all gone now but I'm here to see it," she said, wearing the red and green colours of Sudan in her hair braids.

"It made me very emotional," Amir added.

"I really like the ones that are very woman-empowering, because in my opinion women (took) a very big role in the whole revolution."

Gibril, the organiser, noted some works were anonymously created while others were signed.

"Some of the artists are known and within the ones who are known some of them are missing after the sit-in," she said.

"They were never found so we don't know if they're alive or dead."

'Artists are our biggest weapon'

At least 136 people have been killed in Sudan since June 3, including more than 100 on the day of the raid, according to doctors close the protesters.

The health ministry says 78 people have been killed nationwide over the same period.

"Their bullets will not kill us, what kills is your silence," said another by the exit.
