SAADA, Yemen — The wars have swept through this northern Yemen province like dreaded seasons over the last decade, crushing earthen homes that had survived for hundreds of years and leaving fresh graves that crowd old cemeteries.

The latest war has been the cruelest. In the past six months, aerial bombing by an Arab military coalition led by Saudi Arabia has killed hundreds of people throughout the province and sent thousands fleeing their homes. For a generation of Yemenis, the Saudis, once their country’s biggest benefactor, will be remembered for the destruction they left here, residents say.

But the Saudi adversary, the Yemeni rebel group known as the Houthis, also faces harsh scrutiny for its role in the war. With fury and zeal, Houthi fighters turned their heavy guns on cities and imprisoned opponents. The Houthis drew support from what many saw as a cynical wartime alliance with Yemen’s former leader, Ali Abdullah Saleh.

In Saada, the Houthi stronghold where the rebel movement was founded, frustration abounds with all the combatants in the war.
