Egypt security forces arrested more that 400 people on Tuesday, a day after dozens were killed and injured during clashes in the  capital between supporters of ousted president Mohammad Mursi and security forces.

Health officials said on Tuesday that seven people were killed and 261 wounded in overnight clashes in Cairo.

Two people died in clashes around the central Ramses area near Tahrir Square, while another five were killed in Giza, emergency services chief Mohammed Sultan told AFP, adding that security force personnel were among the injured.

Health ministry official Khaled al-Khatib gave the same toll, cited by the official MENA news agency.

Clashes erupted Monday evening in Cairo's downtown and Giza between police forces and large numbers of Mursi supporters, who intensified their protests while reiterating their demand to reinstate the former elected president.

Later on, security forces arrested more than 400 supporters of Mursi, a security source said on Tuesday.

The 401 arrests were all made in the central Ramses area, where two people were killed in late-night violence, the official MENA news agency quoted the security source as saying.
