At least eleven people were killed and several others wounded in fresh retaliatory attacks in Tana Delta on Thursday morning.
The attacks occurred at Kibisu village where at least fifteen houses have been burnt.
"Eleven people have been killed and 13 others injured," a police officer in the region told Capital FM News.
The officer did not offer much detail "because we are still trying to find out what transpired."
Coast Provincial Police chief Aggrey Adoli confirmed the latest attack. "We have a problem in the area; we will give you all the information once we get it."
Police said tension remained high in the region since the attacks followed Wednesday's killings of ten other people at Nduru area, a few kilometres from the latest attacks.
The Kenya Red Cross said it had deployed its response team from Garsen to the affected area.
