OSLO (AFP) - Half a dozen lawyers filed a complaint in a Norwegian court Wednesday accusing Israels former prime minister Ehud Olmert and nine other top officials of war crimes related to the Gaza offensive. We received the complaint. Were going to study and evaluate it before possibly transferring it to the police, general prosecutor Siri Frigaard told AFP, without elaborating on its content. The lawyers announced Tuesday they would file a complaint demanding the arrest and extradition of Olmert along with former foreign affairs minister Tzipi Livni, Defence Minister Ehud Barak and seven senior Israeli army officers. Under the Norwegian penal code, courts may hear cases involving war crimes and other major human rights violations. The lawyers had previously released a statement accusing Israel of massive terrorist attacks in the Gaza Strip from December to January, killing civilians, illegally using weapons against civilian targets and deliberately attacking hospitals and medical staff. Israels embassy in Oslo refused to comment on the accusations at this stage. Meanwhile, Israeli Foreign Minister Avigdor Lieberman has branded an Arab peace initiative as dangerous because it requires the Jewish state to allow Palestinian refugees to return to its borders, a senior official said on Wednesday. Lieberman considers the Arab peace initiative as dangerous and as a threat to Israel because it includes the clause on the Palestinian refugees, the official told AFP on condition of anonymity. The foreign minister has nevertheless not rejected the initiative as a whole, he said. The Arab peace initiative, presented by Saudi Arabia in 2002, offers Israel full normalisation of ties in return for its withdrawal from occupied Arab land and the creation of a Palestinian state. It also calls for a just solution to the problem of Palestinian refugees to be agreed upon in accordance with the UNGA Resolution No. 194, which the Jewish state has repeatedly rejected.
