The Day in the Gulf

* 2 AMERICANS KILLED, 6 HURT: An American Apache attack helicopter firing Hellfire missiles destroyed two American military vehicles, killing two GIs and wounding six, during a skirmish before dawn, the U.S. Command said. Marine Brig. Gen. Richard I. Neal said the accident occurred under difficult fighting conditions.

* CLASHES AT SAUDI BORDER: American and Iraqi patrols clashed along the border with Saudi Arabia in seven separate engagements between 5 a.m. and 10 a.m. Sunday, the U.S. Command said. In two of the clashes, 20 Iraqi troops surrendered and walked into Saudi Arabia with Apache helicopters guarding them overhead.

* BRITISH ACKNOWLEDGE BOMBING: British military officials said a bomb from a Tornado fighter veered off course into the western Iraqi town of Fallouja during an attack on a bridge last week. Iraq has said that 130 people were killed and 78 wounded when the bomb hit an apartment building and an outdoor market. The British said the bomb exploded in a populated area of the town, but they couldn’t tell what damage was done or confirm Iraqi claims of civilian casualties. Their investigation was continuing.

* BLACK RAIN: A mixture of natural moisture and smoke from petroleum fires fell as black rain along the Iranian frontier, according to Iran’s national news agency. Meanwhile, allied bombers took off into clear skies along the northeastern Saudi coast. But there was rain in the central desert, where some major troop movements were under way.

* UNSAFE PASSAGE: After allied forces said they would not guarantee his safety if he flew to Moscow, Iraqi Foreign Minister Tarik Aziz traveled overland to Iran, then flew to the Soviet capital for his meeting today with President Mikhail S. Gorbachev. Before leaving Tehran, Aziz met with his Iranian counterpart, Ali Akbar Velayati.
