According to locals, the terror group went door-to-door in Lamu County and killed Said Mbigo, Matei Mlatia, Peter Mburu, Teresio Munyi, Mwangangi Muneni, Katana Karisa Chai, and Musyoka Maithya between 5th July and 8th July 2017.
The militants also raided three villages and killed three police officers posted at the Pandanguo police station. Schools in the villages were closed and Christian families were evacuated to a church in Witu town.
Pastor Henry Divayo, head pastor of the church in Witu town, told ICC: "The attackers have been targeting Christians living in Lamu County especially farmers in the interior areas where small-scale agriculture thrives."
He added that the terrorists were "asking the villagers to produce their identification cards and if you were found to be a Christian you would be shot or slaughtered".
Kenya has been aiding the fight against al-Shabaab in Somalia since 2011. In retaliation, al-Shabaab and its supporters have targeted Christians across the border in Kenya.
On 2nd April 2015, the militants targeted Christians and killed148 people at Garissa University College in the north-east of the country. On 12th June 2016, the Islamic terrorists attacked Mpeketoni in Lamu County, killing 48 who couldn't recite verses from the Quran.
ICC's regional manager for Africa, Nathan Johnson, said: "The Kenyan government must provide safety and stability to all of its people. They must end al-Shabaab's reign of terror that has been thriving on the border with Somalia.
"We pray for the families of the deceased and for peace to come to a region that has seen such violence towards Christians. We hope that Kenya's government can take effective action to rid Kenya of these terrorist actions."
The al-Qaida-linked al-Shabab has claimed a growing number of deadly attacks in Kenya as the election approaches, with Kenyan president Uhuru Kenyatta declaring a new offensive against the extremists this month.
