An Irish-Sudanese medical student has spoken of the brutality she has witnessed during the crackdown on pro-democracy protesters in Sudan.

The violence has prompted the United Nations to relocate staff from the country.

More than 100 people were killed in the crackdown on Sudanese protesters carried out by security forces, according to a doctors committee close to demonstrators.

The doctors said the violence started when security forces broke up a sit-in outside army headquarters on Monday.

"To this moment, the total number of deaths that have been accounted by doctors is 101," the Central Committee for Sudanese Doctors said, after reporting that 40 bodies were recovered from the river Nile.

Sara Abdelazim Yousif who went to school in Ennis, County Clare and studied in Galway has lived in Sudan since 2014 and is currently studying medicine there.

She says: "Basically we have had a dictator for 30 years and we've been protesting for years and years but we were met with brutality. Many men and women my father and mother's generation had to seek asylum in different countries for standing up and raising awareness.

"Since the beginning of the year we have been raising awareness and doing public protests. Many were captured including myself and thrown in jail."

She says that on 6 April this year: "The whole nation got up and went to peacefully protest in front of the military grounds. The military said they were on our side.

"I've been camping and taking pictures of the wonderful work they do at the peaceful sit ins. They educate the poor, feed everyone, people give money and take money if they need to get home. People clean up and dance and celebrate freedom."

She adds: "Yesterday was the eve of Eid. They decided to raid the peaceful sit in and start killing people and burning down the tents with people in it.

"Imagine the people there are making cookies to give out and celebrate Eid the next day and they did that. That night 38 people died including a friend of mine."

"Now we are trapped in our homes. We can't leave because they have taken over the city. No shops are open and we can't go out at all. They cut off the internet. No one has internet in the country only a few people like myself and I don't know when it'll cut from me too.

"I'm trying to raise awareness and educate because it's the only thing I can do right now. We can barely receive international calls. They're raising houses stealing and beating and killing innocent people."

She says hospitals in the capital Khartoum are overcrowded with many people being treated on the ground.

Those living nearby have been donating beds from their homes.

However she says one hospital has been infiltrated by the Rapid Support Forces (RSF) with doctors ordered to stop treating patients.

The RSF are a widely feared paramilitary group said to number in the tens of thousands that stands accused of genocide in the Darfur war.
