A group of Sudanese women has been flogged as a punishment for dressing "indecently", according to a local journalist who was arrested with them.
Lubna Ahmed al-Hussein, who 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 several of the women had pleaded guilty to the charges they faced and were lashed immediately.
Khartoum, unlike South Sudan, is governed by Sharia law.
Several of those punished were from the mainly Christian and animist south, Ms Hussein said.
Non-Muslims are not supposed to be subject to Islamic law, even in Khartoum and other parts of the mainly Muslim north.
Ms Hussein said some women pleaded guilty to "get it over with" but others chose to speak to their lawyers and are awaiting their fates.
Ms Hussein is a well-known reporter who writes a weekly column in Sudanese papers called Men Talk.
Human rights groups have called for her release and described her trial as a charade.
