Senegal's Ministry of Communications has shut down cell phone service in the country, citing threats of public unrest, local media reported.
"The Minister of Communication, Telecommunications and Digital Affairs informs the public that due to the dissemination of several hateful and subversive messages relayed on social networks in a context of threats of disturbances to public order, the internet of data mobile phones is temporarily suspended," the released document said.
Numerous users in the capital have reportedly said they have been unable to access mobile data on their phones since the morning.
Earlier, media reported opposition protests in the capital after the president announced the postponement of the elections.
The country's Constitutional Council earlier did not allow arrested opposition figure Ousmane Sonko to run for election.
The president's decision on the postponement of election has raised concerns from the Economic Community of West African States (ECOWAS) Commission and the African Union. The AU Commission Chairman Moussa Faki Mahamat called on Senegal's leadership to hold transparent elections as soon as possible "in a spirit of transparency, peace and national harmony."
Earlier in the day, media reported that Senegalese lawmakers will meet in the capital to discuss a six-month extension of Sall's mandate.
