CAIRO, Egypt — Egypt's protest movement expanded Wednesday as demonstrators encroached on government offices, forcing the evacuation of the Egyptian cabinet building and camping out in front of parliament for a second day, according to government officials and local news.

Thousands of protesters still streamed into Tahrir Square, the nerve center of a mass rebellion that seeks to topple U.S.-backed President Hosni Mubarak.

Also, trade unions -- including those representing railway technicians, public transportation workers, oil workers and workers at several factories -- went on strike throughout Egypt, demanding better wages and improved working conditions, according to local news accounts as well as unconfirmed reports from Egyptian bloggers in and around Cairo.

More than 100 workers at al Ahram, the historic state-backed newspaper, also demonstrated, according to a brief item on the paper's English-language website. They asked for permanent contracts and justice for two colleagues who died in the recent clashes.

"Revolution everywhere in Egypt, revolution in Ahram!" they chanted in the newspaper office's lobby.
