CAIRO — Thousands of Egyptian security forces were deployed across Cairo ahead of the country's first Tunisian-inspired protests on Tuesday.
Egypt's top security official has warned no disturbances would be tolerated.
The protest organizers and opposition supporters — inspired by the popular revolt in Tunisia — have dubbed Tuesday's rallies, which are planned mainly in Cairo and Alexandria, as "the day of revolution against torture, poverty, corruption and unemployment."
The rally call spread on Facebook and Twitter, with 90,000 saying they will attend.
Amnesty International expressed worries over protesters' safety, urging authorities to "refrain from excessive and disproportionate force."
Egypt's Interior Minister Habib el-Adly said "decisive measures" will be imposed in the face of chaos.
