Egyptian police detained 20 members of the Muslim Brotherhood and deployed in force in the capital on Friday, ahead of demonstrations the Islamist group called to protest Israel's offensive in Gaza.
Hundreds of police and agents were deployed around key mosques in Cairo before the protest, which was due to take place after Friday prayers.
A Reuters photographer said police agents were rounding up civilians outside one of Cairo's prominent mosques near the Ramses railway station downtown.
An Interior Minister official declined to comment on the security operation.
The Brotherhood, Egypt's strongest opposition group, said police rounded up at least nine members in four provinces.
"The campaign (of arrests) is still going on," the group said on its website (www.ikhwanonline.org).
The Brotherhood has been leading a broad campaign to end the Israeli-led blockade on the coastal strip.
Israeli attacks have killed more than 400 people.
