About 200 people gathered outside an Istanbul mosque after Friday prayers to protest the killing of Al-Qaeda chief Osama bin Laden by US commandos in Pakistan earlier this week.
The demonstrators rallied at the Fatih mosque in central Istanbul at the call of Islamist newspaper Milli Gazete and with support of the Islamist organization Ozgur-Der.
The mainly male protestors, with a small group of veiled women, brandished banners reading "Terrorist USA, warrior Osama" and chanted "God is great."
The group also carried pictures of bin Laden and US soldiers stopping and searching veiled Iraqi women in the street.
Another banner in English read "We will not forget the crimes of US and Israel."
No incident occurred during the protest.
