Secretary-General Javier Perez de Cuellar will have separate talks with the foreign ministers of Iraq and Iran in Paris this weekend in a bid to move Persian Gulf peace efforts forward, a U.N. spokesman said Friday.

The secretary general and the ministers, Iraq's Tareq Aziz and Iran's Ali Akbar Velayati, will be in the French capital for a conference on chemical weapons. Iraq admitted using such weapons in the eight-year war with Iran that ended last August but also accused the Iranians of using toxic gas against Iraqi troops.Meanwhile, Velayati dismissed an Iraqi charge that Iranian troops had massed on the border and were poised to attack Iraq, saying it was baseless and absurd, the Iranian news agency IRNA said.

Iraqi President Saddam Hussein said in an Army Day broadcast that Iran had concentrated troops along the border and could rekindle the Persian Gulf War.

A U.N.-mediated ceasefire ended fighting between Iran and Iran last August, but troops have not been withdrawn and minor violations of the ceasefire have been reported.
