Tens of thousands demonstrated in cities across Sudan on Saturday, witnesses said, to mark 40 days since security forces killed dozens when they stormed a protest camp in the capital Khartoum.
The demonstrations were the first since the ruling military council and civilian opposition agreed in principle to a power-sharing arrangement ahead of elections. The deal has yet to be finalised and signed.
A meeting between the two sides planned for Saturday was postponed to Sunday, a leader of the Forces for Freedom and Change (FFC) coalition told Reuters. But the military council denied the meeting was being delayed.
At least 128 people were killed during the raid and in the two weeks that followed, according to doctors linked to the opposition. The government confirmed at least 61 deaths.
