Burkina Faso's justice ministry says former prime minister Luc Adolphe Tiao has been arrested and accused of complicity with violence that killed protesters who forced the former president to step down.

The ministry said late Friday that Tiao has been charged with several counts. He was prime minister when a popular uprising forced longtime President Blaise Compaore to resign in late 2014.

The ministry says Tiao is accused of having signed a declaration allowing the army to intervene with the use of weapons to restore calm. About 30 people died and 600 others were wounded in the protests.

Tiao had been in exile in Ivory Coast, along with other ministers from Compaore's regime, before returning to this West African country in recent days.
