ANKARA, Turkey (AP) _ The U.S. Air Force reached agreement with a labor union on Monday to end a 2-month-old strike at NATO bases in Turkey, just three days before a scheduled exercise, the union said.

About 1,800 Turkish workers walked off their jobs on July 23, demanding higher salaries and more benefits at Incirlik Air Base _ the hub of operations for U.S. and British patrol flights enforcing a no-fly zone in northern Iraq _ and at two other bases in Ankara and the Aegean port city of Izmir.

Mustafa Acet, an official of Harb-Is, the Union of Defense Industry and Allied Workers that organized the strike, said workers will return to the job on Wednesday after a vote to ratify the accord on Tuesday.

Acet said the new contract would be signed by Tuesday morning.

He said the agreement compensates workers for wages lost during the strike and includes a 50 percent pay increase and other pay hikes in line with inflation, which currently runs at about 70 percent a year.

The accord comes just days before a planned NATO exercise code-named ``Dynamic Mix 98,'' which will be held jointly in Turkey, Greece and Italy. The exercises will run through Oct. 21.

The strikes have shut down the commissary, gas station, dining halls and other facilities at Incirlik, where 1,446 of the workers were employed. The other bases were affected in similar ways.

U.S. officials were not available for comment.

More than 45 U.S. and British planes monitor Iraq's treatment of the Kurds in northern Iraq from Incirlik, six miles northeast of Adana.
