The authorities in Burkina Faso have said they disrupted access to Facebook due to security fears.
Government spokesperson Alkassoum Maiga said the authorities did not have to explain themselves on the shutdown first reported on 10 January and which appears to have continued.
“I think that if we have a choice between letting insecurity spread and taking measures that allow us to maintain a minimum control over the situation, then the choice seems clear to us that the national interest must take precedence," Maiga said, according to the popular Radio Omega.
The government announced on 11 January that eight soldiers were arrested over a "plan to destabilise the institutions of the republic", a development that local media said was a coup plot.
The internet freedom monitoring group, NetBlocks, reported significant disruptions to internet services on 11 January.
The killing of 53 people by suspected jihadists last November heightened public outrage against the government for failing to end the insurgency. The unrest has heightened fears of a military coup.
