According to BBC news, Lubna Ahmed al-Hussein, a well-known reporter who writes a weekly column called Men Talk for Sudanese papers, who also works for the United Nations Mission in Sudan says she is facing 40 lashes, said she and 12 other women wearing trousers were arrested in a restaurant in the capital, Khartoum.
She said that a group of about 20 or 30 police officers entered the popular Khartoum restaurant and arrested all the women wearing trousers.
"I was wearing trousers and a blouse and the 10 girls who were lashed were wearing like me, there was no difference," she told BBC's Arabic service.
Sudan Tribune reported that ten out of the 13 girls ended up receiving 10 lashes and fined 250 Sudanese pounds while the remaining three asked for their lawyers to be present and as such their cases were transferred to the deputy prosecutor.
The Sudanese journalist told Sudan Tribune that no representatives from the Non-Muslims commission were present considering that the Southern girls were Christians.
Unlike Southern Sudan which has a high proportion of Christians, Northern Sudan including the capital city comes under Sharia 'Islamic' Law.
Under Sharia law in Khartoum, the normal punishment for "indecent" dressing is 40 lashes, a fine or both.
Meanwhile, Washington D.C-based International Christian Concern (ICC) has slammed the Sudanese authorities Wednesday for violating the Comprehensive Peace Agreement (CPA) signed in 2005 by the Islamist government of Sudan and the mainly Christian animist southern Sudanese.
"The agreement provides that Islamic laws are not applicable to non-Muslims living in Khartoum. Khartoum is home to millions of Southern Sudanese who fled the brutal war in South Sudan in which Islamist forces killed 2 million and have displaced 4 million," a news release from ICC stated.
Jonathan Racho, ICC's Regional Manager for Africa and the Middle East said: "Flogging women for wearing pants is both outrageous and against the dignity of the women. Sudanese officials responsible for such illegal acts must be held accountable for this injustice."
Sudan Tribune said the case of Ms Hussein and others is yet to be heard before court.
