Egyptians have been urged to come out after Friday prayers tomorrow and demand the overthrow of Hosni Mubarak's government, along with freedom, justice and a democratic regime.
Anonymous leaflets circulating in Cairo also provide practical and tactical advice for mass demonstrations, confronting riot police, and besieging and taking control of government offices.
Signed "long live Egypt", the slickly produced 26-page document calls on demonstrators to begin with peaceful protests, carrying roses but no banners, and march on official buildings while persuading policemen and soldiers to join their ranks.
The leaflet ask recipients to redistribute it by email and photocopy, but not to use social media such as Facebook and Twitter, which are being monitored by the security forces.
Protesters in Cairo are advised to gather in large numbers in their own neighbourhoods away from police and troops and then move towards key installations such the state broadcasting HQ on the Nile-side Corniche and try to take control "in the name of the people". Other priority targets are the presidential palace and police stations in several parts of central Cairo.
The leaflet includes aerial photographs with approach routes marked and diagrams on crowd formations. Suggested "positive" slogans include "long live Egypt" and "down with the corrupt regime". There are no signs of slogans reflecting the agenda of the powerful Muslim Brotherhood. It advises demonstrators to wear clothing such as hooded jackets, running shoes, goggles and scarves to protect against teargas, and to carry dustbin lids – to ward off baton blows and rubber bullets – first aid kits, and roses to symbolise their peaceful intentions.
Diagrams show how to defend against riot police and push in waves to break through their ranks. "The most important thing is to protect each other," the leaflet says.
It is important to prevent policemen penetrating the ranks of demonstrators, it adds. If they do, they should be persuaded to change sides and reminded that their own families could be among the people.
Banners and posters should be hung from balconies and windows, it advises, and it provides handy models for posters – one showing a visor-helmeted riot policeman flanked by an elderly woman in traditional peasant dress and a younger one in modern clothes over the slogan "Police and people together against the regime".
The president's son Gamal – often thought likely to succeed his father – is labelled "Cowardly Mubarak", with the words "Where's Daddy now?" Another idea is the country's national symbol of an eagle with "Egypt's Liberation Day" underneath it.
