Crowds gather in Tahrir Square amid Morsi defiance

The Egyptian President Mohamed Morsi has appeared on state TV to say he will not step down.

He stressed that he was elected in a free, transparent and democratic way.

However, the unrest shows no sign of abating. The health ministry said that 16 people had been killed and 200 injured at a pro-Morsi rally near Cairo University on Tuesday night.

The BBC's Jeremy Bowen reports from Cairo's Tahrir Square where large crowds gathered once again.
