Amid economic collapse, widespread hunger, and frequent outbreaks of violence, Yemen is not an easy place for anyone to live these days. Much of the country is beyond the government’s control, and most of the population inhabits areas occupied by Houthi extremists. For religious minorities — Hindus, Baháʼís, Christians, and one incarcerated Jew — conditions are especially tenuous. Due to lawlessness and humanitarian issues, the number of foreign Christians has declined in recent years. “A small number may remain, but their position is extremely vulnerable,” said John Ghanim, a Yemeni ex-Muslim turned Christian evangelist now living in the United Kingdom.
