The incident in the village outside Kamar City was just an interlude, but it sounded an alarm for Gao Yang; Yemen is indeed a very complex country. They came to help the Houthis Armed Forces; therefore, they are considered enemies in the eyes of roughly half the Yemeni population.
In fact, aside from a very few people they frequently interact with, regardless of friend or foe, Satan is an outsider in Yemen. Everywhere they go, they are met with hostile and wary glances. As for Eileen and Phoenix, if they don't wear long robes with face veils, they can't even step out, and it's the same even within the Houthis Armed Forces.
Yemen is truly a difficult country for outsiders to develop any liking for because it's not only dangerous but also makes one feel oppressed.
