Fresh strikes and protests have flared in Egypt, where demonstrators are demanding better pay and conditions from their new military rulers.
Bank, tourism, health and transport workers are all staging protests.
In a televised address, the military council has urged all Egyptians to go back to work.
Hundreds of police officers have marched in Tahrir Square in Cairo, saying they wanted to show solidarity with the protesters who toppled President Hosni Mubarak.
They shouted "We and the people are one" and said they wanted to honour the martyrs of the revolution.
There has been another attempt to remove the last protesters from the square, but thousands of people returned waving flags a couple of hours later.
