President Nixon's decision follows peace talks 1973: Nixon orders ceasefire in Vietnam England have President Nixon has ordered a halt to American bombing in North Vietnam following peace talks in Paris. The decision comes after Dr Henry Kissinger, the president's assistant for National Security Affairs, returned to Washington yesterday from France with a draft peace proposal. Representatives from North and South Vietnam and the United States have been at the negotiating table and reports from Paris say progress has been made with compromises on all sides. But many political issues remain to be resolved. Although attacks against the North have been halted, air assaults are continuing against communist forces in South Vietnam, Laos and Cambodia. Communist negotiators in Paris are now calling for the ceasefire to be extended to these areas. President Nixon's special envoy to Saigon, General Alexander Haig, is in the South Vietnamese capital briefing the president on the 25 article peace agreement worked out in Paris. Initial discussions with President Nguyen Van Thieu lasted nearly three hours. Afterwards, the president ordered a five-man delegation to fly to France to consider the proposals in more detail. Reaction in Washington has been cautious. Senator Barry Goldwater, who previously supported the American role in Vietnam, said: "I can't say peace is at hand, but I feel that we're making progress." The Daily Telegraph correspondent in Saigon says President Thieu may feel it is unwise "to jeopardise further American support by holding out against an agreement which Washington considers just".

Stalin encouraged the purges in eastern bloc countries 1953: East German purge begins Artificially 1969: The The East German authorities have begun a purge of senior officials accused of plotting against the state and spying for "imperialistic" powers. Several officers, including the Christian Democratic Foreign Minister, Georg Dertinger, and a number of Jewish politicians, have either been removed or have disappeared in the past few days. The arrests follow a similar purge in Czechoslovakia last November which led to the trial in Prague of 14 senior Communists, 11 of them Jewish, charged with espionage and treason. Former Communist Party General Secretary Rudolf Slansky was among those convicted of plotting against the Czech Government and executed on 3 December. The chief prosecutor at the trial claimed Slansky had had criminal contacts with Israeli agents and that these agents had been interfering in government. Two weeks after the Prague trial it was revealed in Moscow that several doctors, including a number of Jewish GPs, had conspired to poison the Soviet leader Joseph Stalin. The so-called Doctors' Plot coincided with a spate of anti-Zionist propaganda and was followed by a number of arrests as the ailing Soviet dictator tried to bolster his position. Reports today from Berlin say it is not yet clear why Mr Dertinger has been detained, but he was known to be friendly with Otto Fischl, the Czech representative in East Berlin, who was one of those hanged last month. He has always been openly supportive of the Soviet Union but as a member of the East German Christian Democratic Union he was also a supporter of a united Germany. He has been foreign minister since the provisional East German Government was formed in September 1949. Reports say Peter Florin, a Jewish member of the foreign ministry, has also been replaced. It looks as if these arrests are only the beginning of a more widespread purge of political groups and organisations in East Germany. Meanwhile in West Germany there have been mounting protests, especially among right-wing politicians, at the arrest yesterday of several leading neo-Nazis by the British.. The British High Commissioner said those detained were accused of infiltrating West German political parties and were known as the Naumann circle after Dr Werner Naumann, former State Secretary in Goebbel's Ministry of Propaganda. The group of neo-Nazis arrested in west Germany are known as the Naumann circle after Dr Naumann, former State Secretary in Goebbels's Ministry of Propaganda.
