CAIRO  The Egyptian government intensified efforts to crush a fresh wave of protests on Wednesday, banning public gatherings, detaining hundreds of people and sending police officers to scatter protesters who defied the ban and demanded an end to the government of President Hosni Mubarak.

The skirmishes started early in the afternoon, and soon, small fires illuminated large clashes under an overpass. Riot police officers using batons, tear gas and rubber-coated bullets cleared busy avenues; other officers set upon fleeing protesters, beating them with bamboo staves.

Egypt has an extensive and widely feared security apparatus, and it deployed its might in an effort to crush the protests. But it was not clear whether the security forces were succeeding in intimidating protesters or rather inciting them to further defiance.

In contrast to the thousands who marched through Cairo and other cities on Tuesday, the groups of protesters were relatively small. Armored troop carriers rumbled throughout Cairo’s downtown on Wednesday to the thud of tear-gas guns. There were signs that the crackdown was being carefully calibrated, with security forces using their cudgels and sometimes throwing rocks, rather than opening fire.
