DUBAI, UNITED ARAB EMIRATES, NOV. 8 -- An Iranian surface-to-surface missile slammed into the heart of Baghdad today as Arab leaders met in Jordan to debate a united stance against Iran in the seven-year-old gulf war, according to official reports from the Iraqi capital.

An Iraqi war communique tonight said that the Iranian missile had hit a "densely populated residential area of Baghdad, and a large number of innocent civilians were killed."

{An Iraqi military spokesman said the missile killed at least six children and four women, wounded 106 people, and destroyed an apartment building, The Associated Press reported from Baghdad.}

Tehran radio, monitored here, said that Iran had fired two missiles at Iraq's central radio and television building and another "communications center" in Baghdad, but it was not clear what happened to the second missile.

The missile attack was Iran's 17th on Baghdad this year. Today's attack was the first since Oct. 30, and came amid a new escalation in the war over the past 10 days despite diplomatic efforts at the United Nations to arrange a cease-fire.

Iraq claimed last week to have hit six tankers transporting oil from Iran's Kharg Island offshore terminal. It also claimed numerous bombing raids on Iranian oil installations, including an apparently devastating attack on its Japanese-built petrochemical complex outside the port of Bandar Khomeini.

"The rulers of Baghdad intensifed their attacks on Iran's nonmilitary areas on the eve of the Arab summit to give summiteers the impression that Iraq is not in a weak position vis-a-vis Iran," said a spokesman for Iran's Revolutionary Guards, according to Tehran radio.

The spokesman warned that "more crushing attacks" would be unleashed against Iraq so long as it continued its "wicked acts" against Iran.

Today's missile strike against Baghdad was announced only hours after the minister for the Revolutionary Guards, Mohsen Rafiq-Doust, was quoted as saying that Iran was on the threshold of manufacturing its own surface-to-surface missiles copied from the Soviet-made Scud missiles that Iran is believed to have fired at Baghdad previously.

He said, according to a report by the Iranian news agency IRNA, that Iran also was "copying surface-to-air missiles of all kinds and would be able to mass-produce them in the near future."
