An Egyptian court has banned the activities of the Palestinian militant Hamas group, which rules Gaza, and ordered its assets seized.
Hamas has denounced the move, which it said "serves the (Israeli) occupation".
Egyptian officials have accused Hamas of plotting with deposed Islamist president Mohammed Mursi and his Muslim Brotherhood movement to carry out "terror attacks" in the country.
Several Hamas militants have been named among scores of defendants on trial with Mr Mursi for organising jailbreaks and attacking police stations during the 2011 revolt that toppled Hosni Mubarak.
In a separate espionage trial, Mr Mursi and 35 other defendants are accused of conspiring with foreign powers, including Hamas and Iran, to destabilise Egypt.
