Foreign Ministry officials summoned Austria's ambassador in Tehran to a meeting in which they said ''such allegations are tantamount to following Washington'' in its critical line against Mahmoud Ahmadinejad, who won a landslide victory last month, state-run Iranian television reported.

''One should not allow the good relations between the two countries to be disrupted by allegations provided by Zionist elements,'' ministry officials told the ambassador, according to the report.

Austrian prosecutors on Tuesday said they were investigating new information in the 1989 slaying of Iranian Kurdish politician Abdul-Rahman Ghassemlou brought to their attention by an Austrian lawmaker who claims Iran's president-elect was linked to the assassination.

Ghassemlou and two colleagues were gunned down July 13, 1989, in Vienna.

Ahmadinejad has dismissed as ''baseless'' claims that he had any role in the slaying of the dissidents. He has also rejected separate accusations of being involved taking Americans hostage in 1979 at the U.S. Embassy in Tehran - claims made by several of the former captives.

Iran has denounced the claims against Ahmadinejad as part of a campaign engineered by the United States and Israel to smear the new leader, who on Tuesday said the allegations ought to be put to rest.

''The world has to bow down and respect the will of the Iranian nation,'' Ahmadinejad said in a meeting with Foreign Ministry officials, according to the official Islamic Republic News Agency.
