Three people were reported dead as demonstrations against the Mubarak government spread through Egypt Tuesday. In Cairo, Suez and other Egyptian cities, demonstrators took to the streets to challenge police "to employ the same heavy-handed tactics that were the ultimate undoing of the autocratic regime in neighboring Tunisia," the Wall Street Journal reported. Two protesters were killed in a rally in Suez, while a policeman in Cairo died after being hit in the head by a rock.

Police used rubber bullets, dogs, batons and water cannons against demonstrators taking part in a protest called "Day of anger." The group "We are all Khaled Said," named after a businessman beaten to death by police last year, played a critical role in mobilizing the demonstrations.

Demonstrators chanted "Down with Mubarak," "Tunisia, Tunisia" and "Hey Hosni! Hey Gamal! Saudi Arabia is waiting for you." President Hosni Mubarak has ruled the country with an iron fist since the 1981 assassination of President Anwar Sadat, and his son Gamal is considered a likely successor. (Unconfirmed reports said that Gamal and other members of the Mubarak family had fled to the United Kingdom.)

Former Tunisian strongman Zine El Abidine Ben Ali, who fled the country Jan. 14, after more than 23 years in power, is believed to be in Saudi Arabia.

"We have our demands and we're not leaving here until our demands are satisfied," said Shadi Taha of the al-Ghad Party, one of the groups behind the demonstrations. "We've been ruled by Mubarak for 30 years. It's time for him to leave to allow us to push for the real reforms we've been fighting for years."

Calls for demonstrations spread on Facebook and Twitter. By mid-afternoon, there were reports that Twitter had been blocked.

The Muslim Brotherhood allowed its members to participate but said it did not mobilize them to take to the streets.
