Egyptians have held a Rally in Cairo's Tahrir Square

Thousands of Egyptians have held a rally in Cairo's Tahrir square marking the first anniversary of the uprising which toppled President Hosni Mubarak. 

Some are celebrating the success of Islamist parties in the first post-Mubarak elections, while others are calling for further political reforms. The decades-old state of emergency law has been partially lifted to mark the anniversary.
