On the afternoon of November 2 last year, Gebremichael Teweldmedhin, a Tigrayan jeweller and father of nine, headed to work in Gonder, a city in the Amhara region of northern Ethiopia where he had lived for more than three decades. When Gebremichael arrived in the city, he found a mob looting his nephew’s workshop. Gebremichael begged them to stop. Instead, they turned on him.
