NICOSIA, CYPRUS, JULY 25 -- Iran said today its forces killed or wounded more than 1,000 Iraqi soldiers in the first major ground battle since the U.N. Security Council called for a cease-fire last Monday.

The official Islamic Republic News Agency (IRNA), monitored in Nicosia, also quoted a military spokesman as saying Iran shot down an Iraqi Mirage warplane and a helicopter. The state-run Iraqi News Agency, also monitored here, denied any aircraft were downed and did not mention any ground fighting.

{The Iraqi military high command, however, said Iraqi warplanes and helicopters flew 216 combat missions and destroyed 230 Iranian infantry positions and artillery emplacements, Reuter reported from Baghdad. The high command did not say what prompted such intensive raids.}

The conflicting claims of Iran and Iraq could not be resolved immediately. Both sides have rarely allowed foreign reporters to visit the front in the nearly seven-year-old war.

IRNA quoted a field commander as saying Iranian troops repelled Iraqi soldiers who tried to retake two Iranian-held heights in a border region 80 miles northeast of Baghdad. IRNA said there was no word on the fate of the Iraqi pilot of the jet fighter Iran said it shot down.

Previous major fighting was reported last weekend, when Iran claimed it killed or wounded 2,700 Iraqi troops in fighting in the Iranian-held Faw Peninsula in the south and in the northern Kurdistan region.

In Washington, State Department spokesman Pete Martinez said Iraqi Foreign Minister Tariq Aziz would meet Monday with Secretary of State George P. Shultz on U.S.-backed efforts to arrange the cease-fire. Aziz has been in New York for meetings with U.N. Secretary General Javier Perez de Cuellar, who has primary responsibility to carry out the order.

In Taif, Saudi Arabia, foreign ministers from the six Arab nations of the Gulf Cooperation Council, which includes Kuwait, said they backed Kuwait's efforts to protect its shipping from attack. The council's declaration, which did not directly mention the reregistration of Kuwaiti tankers under the U.S. flag, also praised Iraq for its "positive" response to Monday's U.N. Security Council resolution.
