Some scholars favour natural explanations such as a khamsin (sand storm). The federalized Khamsin went on sale in 1975. Fighting continued in the al-Saleh district and along Khamsin Street in the center of Hodeidah. Among her best-selling works were "House of the Seventh Cross", "Khamsin" and "Dark Corridor". The Bora's sales dwindled down; the Khamsin was discontinued between 1982 and 1983. Khamsin is voiced by Rikiya Koyama in Japanese and by Benito Martinez in English.
