As clashes between police and protesters in Cairo's Tahrir Square entered a fourth day, the ruling military council held crisis talks with various political parties in an effort to defuse growing calls for a "second revolution."

Military Field Marshal Hussein Tantawi is expected to address the nation Tuesday amid the growing unrest.

Demonstrators are demanding Egypt's military step down from power after it took over for ousted President Hosni Mubarak. Protesters have been hurling stones at security forces, which fired back with tear gas.

Three Americans were reportedly taken into police custody in Cairo for throwing Molotov cocktails at security forces during the protests.

"There have been a number of reports of Americans being detained, and we are currently looking into that," David Lynfield, a spokesman for the U.S. Embassy in Cairo told NewsCore.
    
Egypt's civilian cabinet offered to resign, but that failed to mollify protesters.

"The goal is to get rid of the government. They're still stealing, and people can't eat," protester Raed Said, 23, said.

"The field marshal has to leave because he's trying to protect Mubarak and doesn't want to try him, so he has to go," he added.

Mubarak's trial, which began in late summer, was suspended at the end of October pending a decision on changing the panel headed by Judge Ahmed Refaat.

Mubarak is charged with complicity in the deaths of protesters killed by Egyptian security forces.

Several dozen people have been killed in the latest protests.
