BEIRUT (AFP) - Four Lebanese university students have been jailed for a week for making crude remarks on the Facebook social networking site about the singing talents of a woman they met at a party, media reports said on Thursday.

Local newspapers reported that the students — all male — were ordered to be detained on January 10 after the young woman’s father objected to the authorities in the eastern town of Zahle.

The four were charged with slander and "violating public morality" and were ordered to be held in preventive detention despite objections by human rights groups.
