Munich , Germany ( CNN ) -- The German diplomat who said there was an assassination attempt against Egypt 's new vice president has retracted his comments . `` I was led to believe that we had a confirmed report but in fact we did n't , '' Wolfgang Ischinger told CNN , adding the information he received was based on an unsubstantiated source . Ischinger , the host of the Munich Security Conference , told a plenary session of the meeting that there was an assassination attempt against Omar Suleiman and several people were killed . At the time , he did n't provide any more detail about the incident . The vice president , appointed last week amid widespread cries for President Hosni Mubarak 's ouster , has been working to initiate a government transition . U.S. Secretary of State Hillary Clinton , who is attending the conference , said it 's important to support the Suleiman-led transition process . Suleiman had been an intelligence chief and a powerful behind-the-scenes player for a long time , and his appointment was seen widely as an attempt by Mubarak to restore order . CNN 's Elise Labott contributed to this report .
