Egypt's government has ordered police to block access to protest camps set up by supporters of ousted President Mohammed Morsi, state TV reports.

Thousands have been defying warnings from the authorities to abandon the sit-ins in Cairo outside the Rabaa al-Adawiya mosque and at Nahda Square.

Human Rights Watch earlier called on the state to "avoid another bloodbath".

The Anti-Coup Pro-Democracy Alliance, a grouping of Morsi supporters led by the Muslim Brotherhood, vowed that the protests would continue.
