HAWZEN, Ethiopia (AP) — Shops remained shuttered, some government workers hadn’t been paid and the town’s main hospital was utterly laid to waste. But the Tigrayan fighters still claimed victory, swaggering through the streets of Hawzen with their guns. It wouldn’t last long. Hawzen, a rural town in the ethnic Tigray region of northern Ethiopia, is a microcosm of the challenge facing Prime Minister Abiy Ahmed _ and a warning that the war here is unlikely to end anytime soon. When The Associated Press arrived in May, Tigrayan fighters had recently retaken Hawzen from Ethiopian government troops, laying claim once again to the contested town.
