NEW YORK (AP) -- McDonald's says a key sales figure slipped again in April, with the world's biggest hamburger chain citing challenging economic conditions around the globe.
The Oak Brook, Ill.-based chain says the figure was down 0.6 percent globally. That included a 0.7 percent increase in the U.S., where it recently introduced its chicken McWraps to attract more customers in their 20s and 30s.
But it fell 2.4 percent in Europe, its biggest market by sales. In the region encompassing Asia, the Middle East and Africa, it was down 2.9 percent. The chain blamed fears over the avian flu for part of the Asian weakness.
Sales at restaurants open at least 13 months is a key metric because it strips out the impact of newly opened and closed locations.
