KUWAIT (AP) _ The Kuwait oil strike will only end if a third party intervenes, a union leader said Thursday.

About 1,200 workers at the state-run Kuwait Oil Co. walked off the job last Saturday, protesting the promotion and wage scales currently in use.

Many complain they have not been promoted in more than 10 years and some have not gotten raises in 18 years.

``A solution cannot be found without a third party because the road between us and them is closed,'' said union leader Mohammad al-Sarhan.

Kuwait produces two million barrels per day of oil. There have been conflicting reports over whether the strike has affected that number.
