McDonald's says a key sales figure fell in October, marking the first monthly drop in nearly a decade for the world's biggest hamburger chain.
The US-based company says global sales at restaurants open at least a year fell 1.8% for the month. The last time the figure dropped was in 2003.
The figure is a key indicator because it strips out the impact of newly opened and closed locations.
After years of outperforming its rivals, McDonald's has seen sales slow recently as the company faces intensifying competition and a persistently weak economy.
