The head of the West African organisation Ecowas has postponed his visit to Dakar where he was due to meet President Macky Sall.
Nigeria's president and head of Ecowas, Bola Tinubu, was due to meet Sall today, Monday.
No new date for the visit has been set at this stage, according to sources talking to RFI.
During the meeting, the Nigerian leader was expected to call on Sall to respect the constitution of his country and to avoid plunging Senegal into a sustained crisis.
This follows protests over the weekend against the postponement of the presidential elections that were due to take place at the end of this month.
Violent clashes with the police resulted in the death of three students in the capital Dakar, and in Ziguinchor in the southern region of Casamance, a stronghold of ex-Pastef leader Ousmane Sonko.
Senegalese voters also protested in European capitals over the weekend.
"The Senegalese took to the streets as they suffer terrible repression from the defence and security forces," Patrice Mendy, representing the Pastef party in France, told RFI.
"The Republic is in danger. This force must rise to establish order. They must serve the Republic, not serve a man or his regime."
Protesters vowed to continue their ongoing actions that left Dakar a virtual ghost town as schools and offices remained closed Monday morning.
The civil society group Aar Sunu Election ("Let's Protect Our Election") will also organise door to door events and caravans.
