At least 20 people have been killed, including 13 soldiers, and several wounded in a series of attacks over the weekend that targeted military barracks and prisons in Sierra Leone, according to the army.

Speaking to reporters on Monday, an army spokesperson said attacks across the capital, Freetown, on Sunday were carried out by “renegade soldiers” but had been repelled. Bangura said the 20 dead included 13 soldiers, three assailants, a police officer, a civilian and someone working in private security. Eight people were wounded and three arrested, he said.

The Reuters news agency, citing a situation report, said about 1,890 people held at the Pademba Road central prison escaped the facility after it was attacked. Police urged those who had escaped to return to the prison.

Reuters said a correspondent saw cell doors forced open or removed entirely during a visit to the facility on Monday, and Colonel Shek Sulaiman Massaquoi, the acting director general of the Sierra Leone Correctional Service, said attackers had rammed through the front gate of the prison in a vehicle after a failed effort to break through with a rocket launcher.
