Troops have moved into Tahrir Square in Cairo, Egypt, to remove protesters.
Several hundred people have been camped in the capital's main square for more than three weeks complaining about the speed of reforms following the overthrow of President Hosni Mubarak in February.
But General Sameh Seif el-Yazal (retired) has told the BBC that it was impossible to meet every demand by the protesters.
President Mubarak is due to stand trial this week on charges of corruption and ordering the killing of protesters.
The BBC reports there are doubts about whether he is well enough to appear.
The main groups have suspended their demonstrations during Ramadan, which began on Monday. Traffic is now moving around the square.
