Iran says it has sent a naval force into the Gulf of Omen to clear mines. Thehran Radio said the operation would begin only if the United Arab Emirates agreed to allow Iranian mine-sweeping forces into their territorial waters. But shortly after the Iranian announcement, the United Arab Emirates turned down the idea, saying they would rely on their own resources and that in any case their coastal waters were now almost clear of mines. Iran had asked to be allowed into the area after several mines were detected in waters off the port of Fujairah. Iran has blamed the United States for laying the mines. However, a BBC correspondent in the area says it is widely assumed the Iranians put them there.
