POLICE in Sudan arrested 13 women in a raid on a cafe and flogged 10 of them in public for wearing trousers.

Wearing of trousers is a violation of the country's strict Islamic law, an official said.

The 13 women were at a cafe in the capital, Khartoum, when they were detained on Friday by officers from the public order police, which enforces the implementation of Sharia law in public places.

The force randomly enforces an alcohol ban and often scolds young men and women mingling in public.

One of those arrested, journalist Lubna Hussein, said she is challenging the charges, which can be punishable by up to 40 lashes.

"I didn't do anything wrong," Ms Hussein said.

Islamic Sharia law has been strictly implemented in Sudan since the ruling party came to power in a 1989 military coup.

Public order cases usually involve quick summary trials with sentences carried out shortly afterward, as was the case with 10 of the women arrested on Friday. They were flogged and fined 250 Sudanese pounds (£74).

Ms Hussein and two other women chose to go to trial. Today, she was summoned for questioning and now awaits a decision from the prosecutor on when the case could go to trial.

Women in northern Sudan, particularly in Khartoum, dress in traditional outfits that include a shawl over their head and shoulder.

Ms Hussein said she decided to speak out because flogging is a practice many women endure in silence. She even sent printed invitations to the press and public figures to attend her expected trial.

"Let the people see for themselves. It is not only my issue," she said.
