Burger King said bringing back its Chicken Fries helped sales jump in the U.S. and Canada by the biggest amount in two years.

The Miami-based chain said Tuesday that global sales rose 2.4 percent at established locations during the third quarter, including a 3.6 percent increase in the U.S. and Canada. McDonald’s previously reported a 3.3 percent decline in the U.S. for the same time, citing heightened competition as a factor.
