ROUGH CUT - NO REPORTER NARRATION
Unrest spreads to Alexandria and Suez, as clashes brake out between riot police and protesters, with reports of at least two deaths.
Clashes erupted between protesters and police, killing two people and wounding hundreds in the biggest security challenge yet for the country's ruling generals days before scheduled elections.
In scenes reminiscent of the 18-day uprising that toppled Hosni Mubarak from three decades of power in February, hundreds youths chanted "The people want to topple the regime" as they rushed towards riot police, who fired rubber bullets and tear gas.
Police fired round after round of tear gas at protesters. Staggered voting is due to begin on Nov. 28 but could be disrupted if violence spreads.
