(CNN) -- Three members of the Mombasa Republican Council, a separatist group, are scheduled to appear on charges of murder in court in Kenya Tuesday in connection with a deadly attack, authorities said.
In the attack, a group of heavily armed men ambushed a police post in the port city of Mombasa, killing at least 10 people, including two police officers Monday, officials said. The three suspects were to be charged with at least four murders, the state council of prosecution said.
David Kimaiyo, inspector general of Kenyan police, said a group of men approached police officers manning a post between 9 p.m. and 10 p.m. and refused to comply with orders to stop. Police fired on the men, who fled into a nearby slum, he said.
When police called for backup, about 200 men ambushed them on a road, Kimaiyo said.
Prime Minister Raila Odinga blamed the attack on the Mombasa Republican Council, a separatist group that wants Mombasa, the second-largest city in Kenya, and its surrounding coastal area to secede.
Stremlau said the violence may have been unrelated to the election.
