Iran had been insisting for about seven months that the German ambassador must be the last of the European Union envoys to return to Tehran. It said Germany should be punished for a Berlin court decision implicating Iranian leaders in the murder of four Iranian dissidents in the city in 1992. But last week the EU reached a compromise agreement with Iran under which its envoys would return in two groups, with the German ambassador, accompanied by his French counterpart, making up the second group. The official Tehran radio said today Iran had achieved its objective and the EU had accepted its conditions: as Iran had insisted all along, the German ambassador was the last European envoy to return, the radio said, describing the outcome as a great victory for the Islamic Republic. It did not mention the French ambassaor, but last week Iran said it only allowed the French envoy to accompany his German counterpart after a direct request from the French foreign minister and in response to a recent two-billion dollar gas deal between Iran and the French company, Total. The Iranian Kurdish Democratic Party, the murder of whose leaders caused the diplomatic row, has condemned the EU decision to send its ambassadors to Iran in two groups. It described the move as a surrendor and accused the European allies of giving their economic interests priority over the fight against terrorism.
