The new flag of Mandera County in Kenya. Based off of a flag posted in the FOTW mailing list, it was officially adopted according  to [1].
Key description of the flag:
"

1. The triangular insert on the left side of the flag symbolizes the Kenyan flag and indicate our commitment to the Kenyan dream and values.
2. The 9 stars inserted in the centre of the flag symbolize the number of Mandera County as 009 in the County listings in the Schedule 1 of the Constitution of Kenya, 2010.
3. The red colour of the flag symbolizes the revolutionary change in governance of the county which is brought about to the county by devolution." Although, I am not too sure how many white fimbriations surround the red star.
