Protesters, security forces clash outside Brotherhood's Cairo HQ

Limited clashes break out for second consecutive day between protesters, security forces outside Muslim Brotherhood's Cairo headquarters

Limited clashes erupted on Sunday evening between protesters and security forces at the Muslim Brotherhood's headquarters in Cairo's Muqattam district.
Hundreds of protesters headed to the group's headquarters on Sunday afternoon to protest an attack against graffiti artists and activists by Brotherhood members on Saturday. Protesters denounced Saturday's attack, especially those on female activists.
Protesters chanted against President Mohamed Morsi and the Islamist group from which he hails, holding banners aloft reading "Down with Brotherhood rule."
Clashes broke out after a group of protesters tried to advance on the group's headquarters, which was guarded by security forces.
The latter used teargas to disperse the crowds, while protesters set fire to tyres in the street.
Several anti-Brotherhood Facebook pages have called on members of the public to march from Cairo's Talaat Harb Square to the Brotherhood's headquarters to protest Saturday's attack on the activists.
According to eyewitnesses, a group of Brotherhood members surrounded the building to protect it.
On Saturday, clashes erupted between Brotherhood members protecting the group's headquarters and a group of activists and graffiti artists who were drawing anti-Brotherhood slogans nearby.
A video circulating online showing female activist Mervat Moses being slapped by a Brotherhood member caused considerable anger among activists and social media users.
Clashes also broke out late Saturday night between protesters and security forces outside the group's headquarters.
