"I am aware that a gang that is unknown attacked Taa village in Witu division yesterday (Monday) night and killed five people," Lamu County commissioner, Stephen Ikua, told Reuters.

Somali rebel group al-Shabab claimed responsibility for last week's attacks on the Mpeketoni area, although Kenyan President Uhuru Kenyatta dismissed al-Shabab's account and said local politicians were behind it.

Taa village is about 40km from Mpeketoni village where last week's deadly attack took place.
