Egypt's security forces were on high alert Monday ahead of pro-democracy protests to mark the second anniversary of former president Hosni Moubarak's ouster, a police official told AFP.

Authorities have boosted security around the presidential palace, the interior ministry and around Tahrir Square, as well as around key public installations, the official said.

Marches are due to set off at 3:00 pm GMT from several locations in the capital towards Tahrir - the epicenter of protests that toppled Mubarak- and the presidential palace.

"There will also be extra security around the main metro stations after some groups threatened to block the tracks," the official said.

Opposition parties and movements have called for a day of action, demanding Egyptian President Mohammad Mursi to fulfill the goals of the revolution that brought him to power.
