KHARTOUM - A Sudanese journalist is preparing to be flogged 40 times in Khartoum on Wednesday for wearing "indecent" clothes, with 10 women already whipped for similar offences against Islamic law.

Lubna Ahmed al-Hussein, who writes for the left-wing Al-Sahafa newspaper and works for the media department of the United Nations Mission in Sudan, was arrested in Khartoum earlier this month after being caught wearing pants.

"I received a telephone call from the authorities saying I must appear at 10 am (0700 GMT) on Wednesday in front of the judge," Hussein told AFP on Tuesday.

"It is important that people know what is happening," Hussein said in an invitation to journalists to attend her court appearance and flogging.

"They will lash me 40 times, and also fine me 250 Sudanese pounds (100 dollars)."

Hussein said she was at a restaurant on July 3 when police came in and ordered 13 women wearing pants to follow them to the police station.
