Solomon Islands police say recent killings continue to be investigated but no arrests have been made.
The deputy police commissioner, Wilfred Akao, says more reports are yet to come in from last week's fatal shooting on the Guadalcanal plain while it has not been possible to send police to the site where a government minister was assassinated last month.
Mr Akao says efforts are being made to restore calm among rival Maliatan people following Monday's violence in Auki which was prompted by rumours surrounding the disappearance of eight people in a motorised canoe.
He says they are yet to be found as the search continues.
Mr Akao says in Honiara, police have not moved against the gunmen who at the weekend seized a ship in response to the rumours.
"It was seized so they could begin consultations - dialogue - about compensation. That is in accordance with Malaita custom."
