TUNIS, Aug 26 (Reuters) - Tunisia's growth this year will not surpass 1.5 percent, a sharp reduction from the official target of 2.5 percent for 2016, Prime Minister designate Youssef Chahed told parliament on Friday.

Tunisia has struggled with lower tourism revenues since Islamist militant attacks targeted foreign tourists last year, forcing cancellations and reducing bookings.
