CAIRO (AP) -- Tens of thousands of Egyptian protesters push past barbed wire fences installed by the army and march on the presidential palace, calling for President Mohammed Morsi to "leave" a day after they say he offered no concessions to opposition demands.
Climbing over tanks of the Republican Guard, protesters streamed toward the palace as night fell Friday, crossing a no-go zone set up around the compound's perimeter.
The area witnessed deadly clashes on Wednesday, when supporters of Morsi's Muslim Brotherhood group drove out crowds camped outside the palace. The clashes left at least six dead and hundreds injured, deepening the schism between the two sides.
Egypt is plunging deeper into crisis as protesters -- mainly liberals-- press Morsi to call off a referendum on a draft constitution agreed by his allies.
