WASHINGTON (AP) _ Leaders of the International Airline Pilots Association are calling for a 48-hour boycott of flights in and out of Syria late next month because of the country's alleged involvement in the attempted bombing of an El Al jetliner earlier this year.

Kelli Zingler, a spokeswoman for the Air Line Pilots Association, the U.S. affiliate of the international union, said pilots from 15 countries are being asked to participate in the boycott, although all are not likely to participate.

She said the call for the boycott was made Tuesday at a meeting of IAPA leaders in London at the request of pilots from Israel and Australia.

No U.S. airlines fly to Syria, Ms. Zingler said.

She said pilots in the following countries, which have airlines that serve Syria, were asked to participate in a boycott: Italy, Bangaldesh, Yugoslavia, the Netherlands, Malta, Kuwait, West Germany, Greece, Austria, Sudan, Switzerland, Turkey, France, Poland and Lebanon.

But she noted that in some of the countries a boycott would be illegal while others are likely not to participate for other reasons.
