TEHRAN -- Italian news agency ANSA highlighted the Iranian President Mohammad Khatami's one-day visit to Afghanistan Wednesday, saying that Tehran and Kabul opened a new chapter of bilateral relations in spite of the U.S. recent accusations of Iran's attempt to destabilize Afghanistan.

Khatami is the highest-ranking Iranian official to visit Afghanistan in four decades, said ANSA adding that, the Iranian president expressed his aversion toward terrorist acts, and termed U.S. war on terror as warmongering.

The Italian news agency also referred to Khatami's request inviting all Afghan parties to support transitional government Head Hamid Karzai.

Tehran-Kabul close cooperation will strengthen friendship, peace and stability in the region, ANSA quoted Karzai as saying.

Iran plans to invest $550 million in Afghanistan to help reconstruct its war-ravaged neighboring state, it said adding that U.S. accused Iran to support Saudi dissident Osama bin Laden's Al-Qaeda network while Tehran strongly opposed the hard-line Taleban.
