Incidents of violence are still being reported in the volatile city amid reports that clashes between gangs of Muslim Hausas and mostly Christian Beroms have now spread beyond Jos to neighboring towns and other parts of the Plateau state. U. S.-based Human Rights Watch says more than 200 people have been killed in three days of violence. So far, Nigerian officials have confirmed only the death of 60 people. The government imposed a 24-hour curfew and ordered troops to act swiftly to stop the fighting. Top police and military commanders are all in Jos to direct security operations in the troubled city. NORTH KOREA North Korea has apparently revalued its currency, in a move that may be aimed at tightening domestic market activity. According to the reports, Pyongyang announced that old North Korean won notes are to be exchanged for new notes at the rate of 100 to one. Citizens will reportedly be ordered to trade in old 1,000-won bills for new 10-won notes this week. North Korea has experienced severe shortages of food, medicine, and other basic needs for two decades, due to the government's economic mismanagement and isolation. North Korea scholars say a black market now flourishes, mainly across the border with China. A number of North Koreans are believed to cross into China regularly to trade and work. This week's currency reform. may be aimed at flushing out earnings from such activities.

N. member countries that voted in favor of it. In a measured and even tone of voice, Mehmanparast stressed Tehran would protest the censure by sending written complaints to the countries that supported it. Mehmanparast added Iran would 'not give up its rights,' to produce nuclear power, and issued a vague threat to take legal action against those trying to prevent it from doing so. BERNE The Swiss Government asked parliament yesterday to ratify a treaty establishing an international criminal court to try mass murderers and other gross violators of human rights. The court, to be based in the Dutch city of The Hague, would try the most heinous crimes—genocide, war crimes and crimes against humanity. 'Setting up a permanent criminal court that aims to put an end to leaving criminals unpunished has been expected for decades. Its creation marks a valuable contribution to peace and security,' the foreign ministry said in a statement. Twenty-two countries have ratified the treaty drawn up in Rome in 1998. A total of 60 must do so before the court can start up. Some 115 countries have signed up for the court, signaling their intention to ratify the treaty. UNITED STATES U.S. officials say they foresee no change in the U. S. dollar's role as the world's primary reserve currency. The statements come in response to calls from China for the establishment of an international reserve currency that is not tied to one country. International unease about the U.
