At least 11 people have been murdered in Kenya in overnight attacks in the capital and its outskirts.
Recent grisly murders have shocked Kenyans
Police say eight people were killed in a Nairobi suburb when gunmen opened fire on drinkers in a bar.
Three others were murdered in Banana Hill, a town about 30km from the capital, one of them was beheaded.
The killings come a day after the ex-leader of the Mungiki, the banned sect blamed for recently beheading some 30 people - was jailed for five years.
The police have not confirmed if members of the outlawed sect were linked to the overnight killings.
The BBC's David Ogot in Nairobi says about five gunmen attacked bar patrons on Thursday night in Kariobangi South, a low income class residential area.
KENYA'S SECRETIVE MUNGIKI
Banned in 2002
Thought to be ethnic Kikuyu militants
Mungiki means multitude in Kikuyu
Inspired by the Mau Mau rebellion of the 1950s
Claim to have more than 1m followers
Promote female circumcision and oath-taking
Believed to be linked to high-profile politicians
Control public transport routes, demanding levies
Blamed for revenge murders in the central region
The gunmen hurled three hand grenades into the bar before shooting indiscriminately at them and people standing outside.
Central Province Commissioner Kiplimo Rugut confirmed that three villagers were killed in Banana Hill township.
Former Mungiki leader John Kamunya, alias Maina Njenga, was sentenced on Thursday to five years in jail by a Nairobi court for possessing a gun and nearly 5kg of marijuana.
Mungiki followers have been demanding protection fees from public transport operators, slum dwellers and other businessmen in Nairobi.
Those who refuse are often brutally murdered.
The Mungiki are thought to be militants from Kenya's biggest ethnic group, the Kikuyu. The sect was banned in 2002.
Some commentators have linked them to politicians wanting to cause unrest and fear ahead of December elections.
