Four members of a Russian family were reported killed in their home in Chechnya, the latest in a string of recent slayings that appear aimed at undermining a peace settlement in the breakaway republic.
Independent NTV television reported Saturday night that unidentified gunmen shot the family members in their home in Grozny, the Chechen capital.
The recent killings began with the deaths of six Red Cross workers who were shot in their beds early Tuesday at a hospital compound in a Chechen village.
On Wednesday, six Russians were fatally shot at two homes in Grozny. Police said they have held 18 people for questioning, but no arrests have been reported.
Chechen law enforcement officials said they detained suspects Friday in the Red Cross shootings, but they have given virtually no information about their identities or said what evidence implicated them.
