Gunmen in Sierra Leone attacked a military barracks and freed hundreds of prisoners in a “co-ordinated and properly planned” attack, the country’s information minister has said.
Sierra Leoneans spent Sunday under a nationwide curfew amid disarray in capital city, Freetown.
A BBC reporter saw armed men on the streets chanting that they would “clean” Sierra Leone.
The attack was a “very serious breach”, Information Minister Chernoh Bah said.
“These were co-ordinated and properly planned attacks on the security and wellbeing of our state,” he told the BBC’s Newsday programme on Monday morning, after the curfew had been lifted.
Current and former military officials were among those involved, some of whom have been detained by security forces.
Addressing suggestions that there had been an attempted coup, Mr Bah said: “We have apprehended some of the major leaders of yesterday’s attack and they are currently being interrogated by our security forces.
“Once they can ascertain the full intent of their actions… we will make a declaration on whether it was an attempted coup.”
Several countries in West and Central Africa are under military rule after a series of recent coups. These include Sierra Leone’s neighbor Guinea as well as Mali, Niger and Chad.
A guard for former President Ernest Koroma was among those detained, a military source told the BBC on Sunday.
Hours later, Mr Koroma said in a statement that one of his guard’s had been killed and another abducted.
He said he “strongly condemned” the violence, in which “Corporal Eddie Conteh was reportedly shot at point blank range while his colleague, Warrant Officer John Swarray was whisked away to an unknown location”.
The information minister echoed President Julius Maada Bio in insisting calm has been restored in Freetown. However, Mr Bah also said a “manhunt” for gunmen and the escaped prisoners is ongoing.
In a televised address on Sunday evening, the president described the events as a “breach of security” and an attack on democracy.
A new nine-hour night-time curfew will begin at 21:00 local time (21:00 GMT) on Monday, the information ministry says.
The political situation in Sierra Leone has remained tense since June, when President Bio was re-elected – narrowly missing out on the need to have a run-off.
International observers have condemned inconsistencies and a lack of transparency in the count, as well as acts of violence and intimidation.
In August, a number of soldiers were arrested and accused of plotting a coup against the president.
The US, European Union, UK and regional block Ecowas have released statements strongly condemning Sunday’s violence.
