DHAHRAN, Saudi Arabia (AP) _ Air raid sirens went off today in this eastern Saudi Arabian city and in Kuwait, but Saudi and U.S. officials said there was no evidence Iraq had fired Scud missiles.

Israel radio broadcast a report that Iraq had launched a Scud at Saudi Arabia, but the army quickly assured jittery residents that the report was false.

Officials said the sirens appeared to be accidental triggerings, but did not elaborate.

A Pentagon official said there was no indication from U.S. early-warning satellites of any Scuds launched. A Saudi aviation official in Riyadh also said the report was erroneous.

The Saudi alarm went off about 11:50 a.m. as reports were emerging about a new air raid on Iraq by U.S.-led allies. Dhahran has the sprawling air base used by U.S., British and French warplanes monitoring Iraq's ''no-fly'' zone in southern Iraq.

In Kuwait, sirens went off near Kuwait International Airport.

Iraq fired 43 Scuds at Saudi Arabia, 39 at Israel, two at Bahrain and one at Qatar during the 1991 Persian Gulf War.
