(AFP) - Two people were killed Monday during protests in southern Senegal after the indictment and detention of opposition figure Ousmane Sonko, a presidential candidate for the 2024 election, the interior ministry said.

Sonko, President Macky Sall's fiercest critic, on Monday was charged with fomenting insurrection and his party dissolved, prompting clashes between protesters and police.

The leading opposition figure has faced a string of legal woes, which he claims have been designed to keep him out of politics and jeopardise his participation in the February 2024 presidential election.

The interior ministry said protests erupted Monday afternoon in the southern city of Ziguinchor where "two lifeless male bodies" were discovered. The ministry press release sent to AFP did got give further details of the circumstances of the deaths in the city where Sonko is mayor.

Less than two hours after Sonko's indictment, the interior minister announced that his PASTEF party would be dissolved for having "frequently" called for insurrection, leading to destruction and the loss of life.

The party slammed the move, saying in a statement that the country's stability was "now compromised", and that the dissolution was "anti-democratic".

- 'Farce' -

Sonko's sentencing in June in absentia to two years in prison in a moral corruption case sparked clashes that left 16 dead according to the government, 24 according to Amnesty International, and 30 according to PASTEF.

He had not been jailed despite that conviction, which rendered him ineligible to stand in next year's election.

On Friday, he was arrested on new allegations tied to comments he has made, rallies he has held, and other episodes since 2021.

The new charges include undermining state security, criminal association with a terrorist body, disseminating false news and theft.

"It's a farce," Cire Cledor Ly, one of Sonko's lawyers, told reporters outside the courthouse on Monday.

"It's a plot that was formed, thought out, planned and executed."

Sonko, who has a passionate following among Senegal's disaffected youth, on Monday continued a hunger strike he began a day earlier, his lawyers said.

They did not say where he would be held.

"I have just been unjustly placed in custody", 49-year-old Sonko wrote on Facebook on Monday afternoon.

"If the Senegalese people, for whom I have always fought, abdicate and decide to leave me in the hands of Macky Sall's regime, I will submit, as always, to divine will", he said.

Sonko was arrested on Friday after claiming on social media that security forces had been filming him outside his house and that he had snatched one of the phones to ask them to delete it.

- 'Resist oppression' -

Sporadic clashes broke out on Monday evening in the suburbs of Dakar, AFP journalists saw.

The demonstrators burned tyres and set up roadblocks while chanting "Free Sonko", before being dispersed by police with tear gas.

Earlier on Monday, authorities announced they were restricting mobile internet access due to "hateful and subversive" messages on social media.

Amnesty International condemned the internet restrictions, calling them an "attack on freedom of information".

The company operating the fast train link between Dakar and its suburbs also said it would halt the line due to "malicious acts" committed by protesters.

"This time I think it's over for Sonko," Sidiya Tall, 34, told AFP. "The young people will certainly go out, but they can't do anything about it."

In Ziguinchor clashes broke out Monday between his supporters and the police, an AFP journalist reported.

Groups of young people threw stones at police, who tried to disperse them with tear gas canisters, the journalist said.

Sonko had called, a day earlier, on Senegalese people to "stand up" and "resist... oppression".

A former civil servant, Sonko rose to prominence in the 2019 presidential election, coming third.

He has portrayed Sall as a would-be dictator, while the president's supporters say Sonko has sown instability.

Sall in early July eased tensions in the normally stable West African nation by announcing he would not seek a controversial third mandate, following months of ambiguity and speculation about his intentions.
