Tens of thousands of protesters have taken part in an unprecedented anti-government demonstration in the Egyptian capital of Cairo.
Opposition activists organised the march on Facebook, drawing inspiration from Tunisia’s recent popular revolt.
President Hosni Mubarak has ruled Egypt for three decades, tolerating little dissent.
“Today is not the start of the revolution. It’s just a rehearsal, to send a strong message,” said Abdel Halim Kandil of the Egyptian Movement for Change.
“We don’t just talk, we do what we say. We can show our people that an uprising is possible,” he told euronews.
The Muslim Brotherhood’s Gamal Heshmat vowed his group would “work to bring about change until our last breath.”
Police used tear gas and water cannons and tried to keep the crowd under control and block their movements.
The Associated Press reported that authorities blocked access to Twitter, which was to be used to give instructions to demonstrators to avoid the police.
euronews’ Cairo correspondent Mohamed El Hamy said the Egyptian opposition are hailing this as a Tunisian-style revolt.
He said: “The protests are shedding light on issues such as corruption, poverty, high unemployment and rising prices.”
