The SL flag is holy.

They made bases in Bali-dhiig. That name should give you hint.
The town is on the border and there was Liyu base on the Ethiopian side. The SL side is the main town and they used to go there to buy necessary goods or mingle with the locals.
But the locals became very angry over the disrespect and insult to the holy flag.
The kids in the town hurled rocks at them and broke their windshields.
Since then they fled and abanoned their base.
