A radical Islamic leader has been detained in Pakistan to prevent him from leading protests against cartoons satirising the Prophet Muhammad.
Thousands took part in street protests across Pakistan
Hafiz Mohammed Saeed was held in Lahore as he prepared for a rally after Friday's prayers, his spokesman said.
More than 100 other protesters have also been detained across Pakistan, amid reports of clashes with police.
At least five people died in Pakistan as rallies against the cartoons in the Western media turned violent this week.
Islamic tradition explicitly prohibits any depiction of Allah or the Prophet.
The cartoons, first published by Danish newspaper Jyllands-Posten in September, have angered Muslims worldwide.
