An eruption of fresh violence triggered by Kenya's disputed presidential ballot left more than 100 dead on Monday, after defeated opposition candidate Raila Odinga rejected Mwai Kibaki's re-election.
Further clashes were feared as Odinga planned to hold his own alternative inauguration at a mass rally later on Monday, a day after Kibaki was officially sworn in for a second term despite widespread allegations of vote-rigging.
At least 64 people were killed overnight in western Kenya in fresh outbreaks of tribal violence and clashes between police, looters and opposition activists.
Separate clashes in the capital Nairobi claimed a further 40 lives, police said.
At least 124 people have now been killed since Thursday's elections, which have left one of Africa's more stable democracies teetering on the brink of turmoil.
The government has enforced a ban on live television broadcasts related to the election in what it says is an effort to contain the violence.
"We know there are skirmishes in many parts of the country. We are fully cracking down and fully responding to every situation," police spokesman Eric Kiraithe told AFP.
A total of 46 bodies were brought to the morgue in Kisumu, Kenya's third largest city and an Odinga stronghold, a mortuary attendant told AFP.
"These bodies were brought here overnight by police officers," he said, adding 20 of them had multiple bullet wounds.
Local police chief Grace Kaindi declined to comment on the number of dead, but acknowledged that police had opened fire on "looters" during the night.
