Egypt unrest: Cairo protesters resolute amid turmoil

Attempts to return Egypt to normality after two weeks of deadly anti-government protests have suffered a number of setbacks.

While banks have reopened, schools and the stock exchange remain closed, and an important government building has been prevented from opening by protesters.

They are occupying Tahrir Square in Cairo, saying they will leave only when President Hosni Mubarak stands down.
