Police in Egypt have detained 25 student members of the banned opposition Muslim Brotherhood.
Security sources say the 25 were arrested during early morning raids Wednesday, in Cairo's Nasr City district.
Authorities say the detainees face charges of belonging to an illegal organization.
Egypt's government banned the Muslim Brotherhood more than 50 years ago but the group operates openly and its members run for political office as independents.
The Islamist group is Egypt's largest opposition movement and controls about one-fifth of the 454 seats in the lower house of parliament.
It says it wants to transform Egypt into an Islamic state through democratic reforms.
