Acting Interior Cabinet Secretary Fred Matiang’i on Saturday imposed a three-month dusk to dawn curfew in Lamu, Tana River and Garissa counties to contain increased attacks by Al-Shabaab militia.
This came hours after the militants horded together and slaughtered nine men in an attack in Jima village, Lamu County.
The Lamu attack came days after another gang killed four police officers in Pandaguo area, looted and burnt valuables.
In a gazette notice, Matiang'i said the order shall be effected from July 9 to October 9, 2017.
President Uhuru Kenyatta chaired a National Security Council meeting earlier on Saturday hours after the news of the attack in Jima came out.
In his brief, the president mentioned the incident but said more details would be provided later.
“We have had an unfortunate incident this morning that we are currently assessing and addressing,” he said.
"This order shall apply during the hours of darkness between the period of 6.30pm in the evening and 6.30am in the morning," Matiang'i said.
Holugho Border Point, Galmagala, Sangailu, Masalani, Bodehei, Milimani, Baure, Basuba, Mangai and Maralani are among the areas where the curfew will apply.
Other areas include Ijara, Hola, Garsen, Kipini, Kiunga and Ishakani/ Dar-es-Salaam Border Point.
Matiang'i however said the curfew excludes the Islands of Lamu, Manda and Pate.
"Every person who resides within this Sub-Counties shall except under and in accordance with the terms and conditions of a written permit granted by the respective Deputy County Commissioner of the affected areas, remain indoors in the premises at which they reside or at such other premises as may be authorised," he said.
