An explosion in Cairo on Sunday evening which killed 20 people was terrorist-related, Egypt's president has said.

A car drove at high speed in the wrong direction, crashing into three others outside a cancer hospital in central Cairo, causing an explosion.

Another 47 people were injured, at least three of them critically, a health ministry spokesman added.

President Abdel Fattah al-Sisi sent condolences to families of those killed in the "cowardly terrorist incident".

(CNN) -- Egyptians swarmed Cairo's Tahrir Square Tuesday, seeking to revive a democratic groundswell that swept the country's former strongman from power nearly two years ago and to demand that the man they chose to replace him respect their wishes.
Protesters waved flags and banners, chanted slogans and called on President Mohamed Morsy to roll back his decree on presidential powers or resign. The crowd included many different Egyptian factions, including Western-style liberals, secularists, moderates and women's rights activists.

CAIRO — Thousands of people flowed into the streets of Cairo, the Egyptian capital, Tuesday afternoon for a day of protest against President Mohamed Morsis attempt to assert broad new powers for the duration of the countrys political transition, dismissing his efforts just the night before to reaffirm his deference to Egyptian law and courts

More than 200.000 filled Cairo's Tahrir square on Tuesday to protest against Egyptian President Mohammed Morsi in escalating unrest over decrees that granted him near absolute powers.
Waving Egypt's red, white and black flags, crowds of protesters marched across Cairo to stream into the iconic plaza, as opposition to the decrees issued last week turned into a broader expression of anger against the rule of Morsi and his Muslim Brotherhood.
