At dawn on Sunday, 25 June 1950, the Korean People's Army crossed the 38th parallel behind artillery fire. The KPA justified its assault with the claim that ROK troops had attacked first, and that they were aiming to arrest and execute the "bandit traitor Syngman Rhee". Fighting began on the strategic Ongjin peninsula in the west. There were initial South Korean claims that they had captured the city of Haeju, and this sequence of events has led some scholars to argue that the South Koreans actually fired first.
Who provoked a conflict by crossing the 38th parallel?
Korean People's Army

At the invitation of the United States government, the Organization for Security and Cooperation in Europe (OSCE) sent a team of observers to monitor the presidential elections in 2004. It was the first time the OSCE had sent observers to a U.S. presidential election, although they had been invited in the past. In September 2004 the OSCE issued a report on U.S. electoral processes and the election final report. The report reads: "The November 2, 2004 elections in the United States mostly met the OSCE commitments included in the 1990 Copenhagen Document. They were conducted in an environment that reflects a long-standing democratic tradition, including institutions governed by the rule of law, free and generally professional media, and a civil society intensively engaged in the election process. There was exceptional public interest in the two leading presidential candidates and the issues raised by their respective campaigns, as well as in the election process itself."
Was this the only occasion the OSCE was invited to preside over a presidential election?
