A huge fire destroyed a clothing factory Saturday in one of seven joint Jordanian-Israeli manufacturing zones in this Arab kingdom, causing several million dollars worth of damage, the official Petra news agency reported. It was unclear what sparked the blaze in the Al Jamal Factory for All-Ready Clothing in the Hussein bin Abdullah II Industrial Qualified Zone in Karak, 216 kilometers south of the Jordanian capital, Amman, early Saturday. Six workers suffering from smoke inhalation were treated at a Karak hospital and all were later discharged but one who was severely injured. No further details were available. Flames tore through 11,000 square meters of the factory's storerooms destroying garments ready for export to the United States, Britain, Israel and Arab countries.
