Dubai's stock market, in a choppy trade, ended higher on Friday ahead of the U.S. Federeal Reserve meeting next week, while the Abu Dhabi index extended losses for a fourth session on price corrections.

Fed policymakers meet next week and are likely to announce a 50 basis point hike in the U.S. central bank's lending rate, while indicating a slower pace of future rate hikes.
